Woman salary is $2,800 in 1988 and was 15% more in 1989. If she paid a tax of 12.5% of her salary, how much tax did she pay in 1

iris [78.8K]

So first step is to find out how much the woman's salary is in 1989. We can do this by multiplying 0.15 (15% in decimal form) and $2,800 together, then adding that product by $2,800.

$2800*0.15= \$ 420\\ 2800+420= \$ 3220$

The woman makes $3,220 in 1989.

To find how much tax she pays in 1989, just multiply 0.125 (12.5% in decimal form) and 3220 together:

$3220*0.125= \$ 402.50$

In short, the woman paid $402.50 in tax in 1989.

Answer:

Regular price of 1 pizza = $15 {Assuming discount coupon = $22.5}

Let regular non discounted price of 7 pizzas be x

x - 22.5 = 82.5

x = 82.5 + 22.5

A 4-pound bag of sugar contains 454 one-teaspoon servings and costs $3.49. A batch of muffins uses 1 2 cup of sugar. How many wh

grin007 [14]

Answer:

a) 19 batches

b) $0.18

Step-by-step explanation:

A 4-pound bag of sugar contains 4 54 one-teaspoon servings and costs $3.49. A batch of muffins uses 1/2 cup of sugar.

1 cup = 48 teaspoons

a) How many whole batches can you make if you use as much of the sugar as possible?

1 batch = 1/2 cups of sugar = 24 teaspoons of sugar

Hence,

24 teaspoons of sugar = 1 batch

454 one-teaspoon servings = x

Cross Multiply

24 × x = 1 × 454

x = 454/24

x = 18.9166666667

Approximately to whole batches = 19 batches

b) What is the cost of sugar for each batch?

454 one-teaspoon servings and costs $3.49 = 19 batches

Hence

19 batches = $3.49

1 batch = x

x= $3.49/19

x = $0.18368421052

Approximately = $0.18
