Increase by 28% means original+28% of original
28% of original is 0.28 times original

so
original+0.28 times original=1 times original+0.28 times original
undistribute original
original(1+0.28)
original(1.28)

so multiply it by 1.28 to incrase by 28%

c. This budget can be modified by reducing the amount spent on food and clothes, thereby reducing overall expenses to have the maximum amount of money for fixed expenses and maintaining a positive actual net income.

You can't reduce fixed expenses. These are expenses that are constant every month like rent expense, utility payments, and cell phone plan. The only expenses you can reduce are food and clothes. These expenses are called variable expenses meaning the amount of these expenses varies. Thus, it can be manipulated.

Tonya went out to a restaurant for lunch. She tipped 12% of her bill, which brought the sum of the lunch bill plus the tip to $28. How much was the original bill?

Tip = 12% × bill

$28 = tip + bill

$28 = bill + 12% × bill
$28 = bill (1 + 12%)

bill = $28÷(1+12%) = $25

Which number can each term of the equation be multiplied by to eliminate the fractions before solving? m – = 2 + m

This is the concept of algebra, to solve the expression we proceed as follow;
m-=2+m
this can be written as:
-m=2+m
-m-m=2
-2m=2
multiply both sides by -1/2
-1/2(-2m)=2*(-1/2)
m=-1
the answer will therefore be m=-1

QUESTION POSTED AT 17/10/2019 - 07:44 AM

What is the percent increase if your salary went from $95 to $100 per week? Round your answer to the nearest tenth, if necessary.

Answer:  The required percent increase is 5.3%.

Step-by-step explanation:  We are given to find the percent increase if your salary went from $95 to $100 per week.

The percent increase will be equal to the increment in the salary divide by the  old salary multiplied by 100%.

The increment in the salary is given by

I=\$(100-95)=\$5.

Therefore, the percent increase is given by

\dfrac{I}{95}\times100\%=\dfrac{5}{95}\times100\%=\dfrac{100}{19}\%=5.26\%.

Rounding to nearest tenth, we get

Percent increase = 5.3%.

Thus, the required percent increase is 5.3%.

Can 12 cm 12 cm and 28 cm form a triangle

Using the Theorem of Pythagoras (a² + b² = c²)

Put in the values:

12² + 12² = 28²
Is it correct? (solve)

Nope! Because 12² + 12² = 288, and the square root of 288 is about 17, not 28.

The answer is no, 12cm, 12cm, 28cm cannot form a triangle.

QUESTION POSTED AT 17/10/2019 - 07:14 AM

Calculate the percentage change (increase or decease) that occurs when: a) 25 becomes 60 b) 66 becomes 30 Please show workings out and/or explain.

The first step is to find the CHANGE. This is done by subtracting the two values and taking the absolute value. Next step is to find the ratio of the change to the original and multiplying by 100% to make it a percentage.

So;

a)  change = Ι60 - 25Ι = 35.

     ratio of change to original = 35:25,

    multiplying by 100% will give 35/25 × 100% = 140%.

    Hence it is a 140% INCREASE.

b) change = | 30 - 66 | = 36

    the ratio is 36:66

multiplying by 100% = 36/66 × 100% = 0.545454... ×100% ≈ 54.5%

   Hence it is a 54.5% DECREASE.

QUESTION POSTED AT 17/10/2019 - 07:02 AM

Diana can use the equation y = 7x to calculate her pay, where y represents the amount of pay, and x represents the number of hours worked. How many hours did Diana work if she was paid $45.50?

Well from the equation $45.50 represents y (in this case) and now you're finding x.

      y = 7x

      45.50 = 7x    Divide both sides of the equation by 7 to find x.

      45.50/7 = 7x/7

      6.50 = x

Hence she worked 6.5 hours (or 6 hours 30 minutes.)
