A record sells for $7.98. Johann bought one on sale for $5.98. Estimate the amount saved as a percent of the regular price.

Answers

Answer:

25.06%

Step-by-step explanation:

We can use the percentage formula for this problem:

p = 100(y/x)

Let's simplify it:

p = 100(5.98/7.98)

p = 100(0.7494)

100 * 0.7494 = 74.94

100.00 - 74.94 = 25.06

Therefore, Johann saved 25.06% on the record.

24x4+92x−11x=11x−11x

24x4+81x=0

Step 2: Factor left side of equation.

3x(2x+3)(4x2−6x+9)=0

Step 3: Set factors equal to 0.

3x=0 or 2x+3=0 or 4x2−6x+9=0

Angelina has a recipe for chocolate cookies. She uses 2 1/2 cups of flour to make 4 dozen cookies. Luke will follow the same
recipe. He will make ddozen cookies using f cups of flour. Which of these equations represents the relationship between
d and f?

Answers

Answer:

d = 5/8f

Step-by-step explanation:

You have the ratio 4d = 2 1/2f, so all you have to do is simplify this equation:

4d = 2 1/2f

divide both sides by 4

d = 5/8f.

(This represents that each dozen uses 5/8 of a cup of flour)
