She wants to purchase shoes that cost $ 50
she wants to purchase socks that cost 2.20 each......so the expression for this is 2.20s...with s being the number of pairs of socks bought
and she only has $ 64....so she has to spend 64 or less...< = 64
so ur inequality would be :
50 + 2.20s < = 64.....subtract 50 from both sides
2.20s < = 64 - 50
2.20s < = 14...divide both sides by 2.20
s < = 14 / 2.20
s < = 6.36....so she can purchase 6 pairs of socks without going over
9x+27+15x
24x+27
Nine times x equals nine x. Then nine times three equals twenty-seven. Combine nine x and fifthteen x and you get twenty-four x.
