Two functions are shown in the table below.
SVETLANKA909090 [29]

Answer:

(d)\ x = 4

Step-by-step explanation:

Given

f(x) = -x^2 + 4x + 12

g(x) = x + 8

Required

Find x such that: f(x) = g(x)

This gives:

-x^2 + 4x + 12 = x+8

Collect like terms

-x^2 + 4x -x + 12 -8=0

-x^2 + 3x +4 =0

Expand

-x^2 + 4x - x+4 =0

Factorize

x(x - 4) - 1(x-4) = 0

Factor out x - 1

(x- 1)(x - 4)=0

Solve:

x =1\ or\ x = 4

Number of boxes = 100/(5/4) = 80 boxes

Cost of one box = $1.75

Total selling price = 80×1.75 = 140

The total selling price for all the boxes of chocolate is $140
