Write an equation to determine how many pairs of shoes, p, Roger must sell in a day to meet his daily earnings goal:
4.50p + 40 = 112
Find the number of pairs of shoes he must sell to meet his daily earnings goal:
16 pairs of shoes
Explanation:
$40 per day
$4.50 per shoe
$112 is earning goal
p = # of shoes he needs to sell, to get to goal
to find p we have to isolate p
4.50p + 40 = 112
subtract 40 from both sides
4.50p = 72
divide both sides by 4.50
p = 16
Roger needs to sell 16 shoes each day in order to achieve his goal of earning $112 each day.
