Question

Willow babysits for $30 an day, but has to spend $4.25 a day for gas. The rest of the money she puts in her new savings account.

Tyler makes $6.50 scooping ice cream each day and saves all his earnings. He currently has $120 in his savings account.


How many days must Willow work to have more more money in the bank than Tyler?

Answer 1

7 Days

Explanation:

Willow makes $30 a day, but spends $4.25 a day for gas. This means she puts $25.75 into her new savings account daily ($30.00 - $4.25 = $25.75)

Tyler makes $6.50 daily scooping ice cream and puts all of it into savings. He has $120 in his savings account right now.

So, taking the amount she spends on gas into account, Willow banks $25.75 a day. Tyler banks $6.50 a day, with $120 currently in his savings account.

Willow: $25.75 x 6 = $154.50

Tyler: ($6.50 x 6) + $120 = $159.00

After 6 days, Willow is $4.50 behind in savings compared to Tyler, so she must work more than 6 days.

Willow: $25.75 x 7 = $180.25

Tyler: ($6.50 x 7) + $120 = $165.50

After 7 days (1 week), Willow is $14.75 ahead of Tyler. Therefore, Willow must work 7 days to have more in the bank than Tyler.

Hope this helps.
