Question

Susan borrowed $19 from her brother. She paid him back $3 the next day. She will then give him $4/week to pay off the debt. How many weeks will it take to pay?​

Answer 1

The answer to this is 4 weeks

Explanation:

3 + 4 + 4 + 4 = 19

first add 3 and 4 = week one

and then 7 + 4 = week 2

next 11 + 4 = week 3

lastly 15 + 4 = 19 = week 4

Answer 2

19

Explanation:

Let w represent the number of weeks. Cali is paying off $4/week and has already paid $3. The total she will pay is 4w + 3. She owes a total of $19. 4w + 3 = 19
