Jacob saved 60 cents a day. On the ninth day after he had started saving, Jason started saving $1 each day. How many days did Jason take to save the same amount of money as Jacob?
$0.60 x 8 = $4.80 Amount Jacob saved before Jason started saving
$1.00 - $0.60 = $0.40 Difference in savings per day
4.80 ÷ 0.40 = 12 days Number of days for Jason to catch up
Jason took 12 days to save the same amount of money as Jacob.
