Question

Tina is saving to buy a notebook computer. She has two options. The first option is to put $200 away initially and save $10 every month. The second option is to put $100 away initially and save $30 every month. After how many months Latina say the same amount using either option? How much would you save with either option?

Answer 1

You would save $250 which either option

Answer 2

200 + 10m = 100 + 30m
200 - 100 = 30m - 10m
100 = 20m
100/20 = m
5 = m....she will have saved the same amount at 5 months <==

200 + 10(5) = 200 + 50 = 250
100 + 30(5) = 100 + 150 = 250
she would have saved $ 250 <===
