The amount, A (in dollars), that she still needs after w weeks is given by the following function. =Aw−50017w Answer the following questions. (a) If Hamdah still needs $211, how many weeks has she been saving? weeks (b) How much money does Hamdah still need after 5 weeks? $

Answer 1

If Hamdah still needs $211, she has been saving for 17 weeks(17b). Hamdah still needs $126 after 5 weeks

Explanation:

Subtract $211 from $500, you will get $289. After you must divide $289 by 17 because Hamdah earns $17 each week, you will get 17 and that represents how many weeks she has been saving. Hamdah still needs $126 because taking the information from the last question she has $289 (289+211 equals 500, 211 is how much she needs and 289 is how much she has) so we subtract 289 from 500 and we will get 211, then you subtract the product of $17 × 5 weeks from 211 and you will get $126. So, after 5 weeks, Hamdah will still need $126.

Answer 2

(a) 14.11 dollars (b) 204 dollars

Explanation:

(a) 500 - 211 = 289 289 '/. 17 = 14 r:7 14.7 dollars

(b) 17 x 5 = 85 289 - 85 = 204
