Answer:

3 sandals 2 sneakers

Step-by-step 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
