So you aren't actually finding her age, you're just finding an equation that could be used.

ok
OpenStudy (anonymous):
so i think the answer is c
OpenStudy (horsegirl27):
So four times Amy's age, x = 4x. And then we know Ava's age is 5 less than 4x, and less than means subtract. That leaves you with 4x-5!
OpenStudy (anonymous):
so i got it right
OpenStudy (horsegirl27):
4x-5 is written as B.
