Question

he 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

A. {50.55, 63.45, 80.34, 99.8}B. {43.45, 58.75, 73.4, 93.5}C. {56.35, 70.55, 81.2, 116.7} D. {45.74, 65.7, 83.8, 105.7}E. {63.25, 68.35, 79.7, 97.6}

Answer 2

I added 4 to 17 to get 21 so now f(x)=3.55 and {21, 25, 28, 38}

Answer 3

Then I multiplied 3.55 by 4 to get 14.2

Answer 4

you have {17, 21,24,34} those are your x values, on the equation substitute the x for 17 and see what you get, then do the same with the other numbers.

Answer 5

so you have 3.55(17) -4 = ????

Answer 6

Now multiply the solution set by 14.2
21(14.2)=241.4
25(14.2)=355
28(14.2)=397.6
38(14.2)=539.6
{241.4, 355, 397.6, 539.6}

Answer 7

Now plug the other numbers into the original formula.
