Answer:
he bought 16 pairs of shoes
Step-by-step explanation:
....
y=4.5x+40
16 pairs of shoes
Let the target earnings be represented by y and the number of pairs of shoes that Roger sells be x hence
The equation is therefore, y=4.5x+40.
To solve this equation, substitute the value of y with 112 hence
112=4.5x+40
4.5x=112-40=72
x=72/4.5=16
Therefore, Roger should sell 16 pairs of shoes to achieve his target earnings of $112

10%
if he has 60 boxes then it would be 60/600
simplify that to 6/60 which further simplifies to 1/10 which is 10%
