Answer:
$89.25
Step-by-step explanation:
If one week is 29.75, then you can infer that each week separately would be the same amount. With this information, you can form this equation:
y = 29.75x
X would be the number of weeks while y would be the final amount based off the number of weeks.
If you substitute x with 3, then you should get the final answer of 89.25.
Hope this helps!
