Answer:
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.
