Question

If many paintings does jill own? (1) if jill sells 5 of her paintings then she will own fewer than 24 paintings. (2) if jill buys 5 more paintings then she will own at least 32 paintings.

Answer 1

Set-up equations

x - 5 = 24

x + 5 = 32

Combine

x-5+x+5= 56

-5 + 5 = 0

2x = 56

Solve for x

2x/2 = x

56/2 = 28

Answer

x = 28

Jill owns 28 paintings
