Amount of money in the hand of Wade = $175 Cost of each sweater = $12 Amount of money that needs to be in the hand of Wade after buying sweater = $55 Let us assume the number of sweaters that Wade can buy = x Then 12x + 55 = 175 This is the inequality equation that has to be solved to find the number of sweaters that Wade can buy. So 12x + 55 = 175 12x = 175 -55 12x = 120 x = 120/12 = 10 So Wade can buy a total of 10 sweaters and still have $55 in his hand. I hope the procedure of doing this problem is clear to you.
So you want to change the - into a + and the negative sign before the 13 also into a plus. So it is -29 + 13 and that would be -16 ^.^ Hope this helped!!
