Tickets for a school event were $2.75 for students and $3.25 for parents. If a total of 67 tickets were sold for $202.25, how many student and parent tickets were sold?
There were student tickets sold and parent tickets sold.

Parents = 36

Sudents = 31

Step-by-step explanation:

x + y = 67 (1)

x = 67 - y

2.75x + 3.25y = 202.25

2.75 (67-y) + 3.25y = 202.25

184.25 - 2 75y + 3.25y = 202.25

0.5y = 18

y = 36

From (1)

x + 36 = 67

x = 67-36 = 31

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
