Answer:
The answer to this is 4 weeks
Step-by-step 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
19
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
-17 =s
-8s +4 = -7s +21
Add 8s to each side
-8s+8s +4 = -7s+8s +21
4 = s+21
Subtract 21 from each side
4-21 = s+21-21
347
2(3) + 210 = 216
2(3) + 125 = 131
216+131 = 347
