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?
{50.55, 63.45, 80.34, 99.8}



{43.45, 58.75, 73.4, 93.5}



{56.35, 70.55, 81.2, 116.7}



{45.74, 65.7, 83.8, 105.7}



{63.25, 68.35, 79.7, 97.6}

Answer 1

Answer:

For those who didn't understand how he was doing this its C.

Step-by-step explanation:

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

Answer 2

F(x) = 3.55x - 4...17 customers....17 = x
f(17) = 3.55(17) - 4 =
f(17) = 60.35 - 4 = 
f(17) = 56.35

f(x) = 3.55x - 4...21 customers....21 = x
f(21) = 3.55(21) - 4 =
f(21) = 74.55 - 4 = 
f(21) = 70.55

ok...I think u can see how I am doing this...answer should be easy to find..lol
