first, find out how much stan gets per week.
.25 x 7 =1.75
now how much they get together
1.75 + 1.20 = 2.95
and then the final step
23.60 / 2.95 = 8
it'll take 8 weeks for them to buy the model car set
Jim and Stan will need approximately 8 weeks to save enough money to buy the model car set that costs $23.60. They combine their weekly allowances to reach a total of $2.95. By dividing the total cost by their savings rate, we find that it takes 8 weeks to save the required amount.
