Question

The money collected from selling bacon at a butcher store is given by the function f(x) = 3.55x – 4, where f(x) is the sales revenue in dollars and x is the number of customers visiting the store each day. If {17, 21, 24, 34} customers visited over four days, what is the income from bacon sales each day?

Answer 1

it is {50.55, 63.45, 80.34, 99.8}

Answer 2

f(x) = 3.55x - 4

Day 1, x = 17

f(17) = 3.55(17) - 4 = 56.35

Day 2, x = 21

f(21) = 3.55(21) - 4 = 70.55

Day 3, x = 24

f(24) = 3.55(24) - 4 = 81.2

Day 4, x = 34

f(34) = 3.55 (34) - 4 = 116.7
