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.
