Answer: -0.5c
Step-by-step explanation: multiply -2.5 by 1/5 (0.2) and you get -0/5
Total tickets sold = 159
Total sales = $1100.60
Child admission = $5.20
Adult admission = $8.90
Assumed all 159 tickets are Child admission tickets
Total sales = 159 x 5.2 = $826.80
Difference in amount = $1100.60 - $826.80 = $273.80
The difference must be contributed by the Adult Admission Tickets, which has a difference of $8.90 - $5.20 = $3.70
$273.80 ÷ $3.70 = 74 adult tickets
159 - 74 = 85 child tickets
702.6
I found this from middle school math.
Sorry I can't help with the formula to work it into simplest form but the answer is 6 pieces of clay :(
