Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes he sells in a day. his daily earnings goal is $112. write an equation to determine how many pairs of shoes, p, roger must sell in a day to meet his daily earnings goal. find the number of pairs of shoes he must sell to meet his daily earnings goal.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
