Answer:
5050 = 225f + 125p
If p = 17 this month, then, f = 13
Step-by-step explanation:
Kiri owns a coworking space that has two primary types of memberships, full time and part-time. In order to pay her bills each month (rent on the building, electricity, internet, and so on) she needs to make $5050. Full-time memberships (f) cost $225 per month, and part-time memberships (p) cost $125 per month.
If Kiri has 17 part-time members this month, how many full-time members does she need according to your equation?
Total cost = $5050
cost of full-time memberships = $225
number of full time members = f
cost of part-time memberships = $125
number of part-time members = p
Total cost = cost of full-time memberships * number of full time members + cost of part-time memberships * number of part-time members
5050 = 225f + 125p
If p = 17 this month,
5050 = 225f + 125p
5050 = 225f + 125(17)
5050 = 225f + 2,125
5050 - 2,125 = 225f
2,925 = 225f
f = 2,925/225
f = 13
number of full time members = f = 13
If p = 17 this month, then, f = 13
