Question

Fred earns $6.50 an hour, plus tips, as a waiter. Suppose he works 26 hours in a week. How much money must he receive in tips to earn at least $229 that week?

Answer 1

To solve this problem, we set up an equation for the problem statement. We let x as the number of hours Fred works and y as the tips he earned. The equation would be:

6.50x + y = 229

Since we are given the number of hours he worked which is 26 hours. Therefore, we can solve for the tip he should earn.

6.50(26) + y = 229
y = 60

Answer 2

Fred's total earning is the sum of its wage and the tips. Let x be the amount he must receive in tips. This value should be equal or greater than 229. The inequality that represents this is,
($6.5)(26) + x ≥ 229
The value of x is 60. Therefore he must receive at least $60 as tips.
