Corey spends 16% of his salary on food each week. If his salary is $800 per week, how much does Corey spend on food each week?

Write an equation with ratios. Use c for the unknown value.
____ = ____
800 100
Corey spends $ on food each week

128

c/800 = 16/100

so c = 8 * 16

128

To find out how much Corey spends on food each week, we can set up a ratio using percentages. Let's let c represent the unknown value (how much Corey spends on food each week).

The given information tells us that Corey spends 16% of his salary on food each week. Since 16% is equivalent to 16/100 or 0.16 as a decimal, we can write the equation:

c/800 = 0.16/1

To solve for c, we can cross-multiply:

1c = 0.16 * 800

1c = 128

Therefore, Corey spends $128 on food each week.
