Currently, Tyler has $60 and his sister has $135. Both get an allowance of $5 each week. Tyler decides to save his entire allowance, but his sister spends all of hers each week plus an additional $10 each week. After how many weeks will they each have the same amount of money?

Number of week same amount of money (W) = 5 week

Step-by-step explanation:

Given:

Amount Tyler have = $60

Amount Tyler's sister have = $135

Amount of allowances get = $5 per week

Amount sister spent per week = $10

Find:

Number of week same amount of money (W)

Computation:

Amount Tyler have in W week = 60 + 5(W)

Amount Tyler's sister have in W week = 135 -10(W)

So,

60 + 5W = 135 - 10W

15W = 75

W = 5

Number of week same amount of money (W) = 5 week
