Question

every weekend, morgan buys interesting clothes at her local thrift store and then resells them on an auction website. If she brings $150.00 and spends s, write an expression for howo much change she has. Evaulat eyour expressioon for s=$27.13 and s = $55.14

Answer 1

The expression that can be used in order to express the amount of money that Morgan has after spending s will be,
   
   x = 150 - s

where x is a variable that we can use in order to denote the amount she will have left, 150 is the original amount of money as stated in the problem and s is the amount spent. 

For the evaluation, we simply have to substitute the given values in place of s and calculate for the value of x.

(1)   s = $27.13
    x = 150 - 27.13
    x = $122.87

(2)  s = $55.14
   x = 150 - 55.14
   x = $94.86
