I FOUND YOUR COMPLETE QUESTION IN OTHER SOURCES. PLEASE SEE ATTACHED IMAGE. For this case we have the following variable: p = number of pairs of shoes The equation that represents the problem is: f (p) = 4.50p + 40 To achieve your daily goal we have: 4.50p + 40 = 112 We clear the value of p = 4.50p = 112-40 p = 72 / 4.50 p = 16 (pair of shoes) Answer: an equation to determine how many pairs of shoes, p, Roger must sell in a day to meet his daily earnings goal is: f (p) = 4.50p + 40 the number of pairs of shoes he must sell to meet his daily earnings goal is: p = 16 (pair of shoes)
