Make an equation system based on the problem
<span>Jason and Mara have $74
</span>⇒ j + m = 74
<span> Jason has $6 more than 1/3 as much money as Mara has
</span>⇒ j = (1/3)m + 6
<span>
Then, solve the equation by subtitution
j + m = 74
(1/3)m + 6 + m = 74
(1/3)m + m = 74 - 6
(1/3)m + (3/3)m = 68
(4/3)m = 68
m = 68 </span>÷ 4/3
m = 68 × 3/4
m = 51
Mara has $51
j + m = 74
j + 51 = 74
j = 74 - 51
j = 23
Jason has $23

Answer:
he will have 8,829 dollars after 3 summers
Step-by-step explanation:
by using the cross multiplication method you can calculate how much interest is gathered after each year
eventually after 3 summers interest has built up he would have 8,829 dollars including the 2,700 he earned each year
Let us say that this number is n
Then we could say:
<em><u>n - 9</u></em>
