Question

Admission to a local aquarium is $10 for adults and S7 for children. The aquarium collected $6,459 from the sale of 783 tickets. How many childrens tickets were sold?

(1) 326
(2) 362
(3) 417
(4) 457​

Answer 1

The answer is 457

Explanation:

You set up an equation as

10a+7c=6459

a+c=783

c= child

a= adult

then you simplify to 3a=978 by taking out one of the values. You get a - 326.

783-326=457 so there is your answer
