Question

The formula that the Diamond Company uses to estimate its monthly office supply expenses is y 10.50x + 100, where x is the number of people working in the office that month and y is the total monthly office supply expense. If the office supply estimate for January is $362.50, how many people are working in the office that month?

35 people
25 people
4 people
12 people

Answer 1

Explanation:

first plug 362.50 in for y since that is our office supply expense

362.50 = 10.50x + 100

then we solve for x

362.50 = 10.50x + 100

262.50 = 10.50x

25 = x

so 25 are working in the office that month
