Question

A pair of sneakers cost $45 and a pair of sandals cost $20. I bought 5 pairs of shoes and spent a total of $150. How many of each kind of shoes did I buy? Let x = 1 pair of sneakers Let y = 1 pair of sandals Equations: 45x + 20y = 150 x + y = 5

Answer 1

3 sandals 2 sneakers

Explanation:

i’m not sure how to do it with the equation but start by writing:

sandals sneakers

1= $20 4=$180

2= $40 3=$135

3= $60 2=$90

4= $80 1=$45

if 1 pair of sandals = $20 then 2= $40 etc

if 1 pair of sneakers = $45 then 2=$90 etc

cancel out all the sums that don’t add up to $150 eg.

80+45= 125 (incorrect)

so in the end you will get to:

$60+$90= 150

3sandals + 2sneakers =150
