​ math homework for 8th

Question

On a certain hot​ summer's day,

155

people used the public swimming pool. The daily prices are

$1.25

for children and

$2.00

for adults. The receipts for admission totaled

$259.00.  

How many children and how many adults swam at the public pool that​ day?

Answer 1

1,25C + 2A = 259

C+A = 155

1.25C + 2(155-C)= 259

.75C = 51

C = (4/3)51 = 4(17) = 68 children

A = 155-68= 87 adults
