step-by-step explanation:

f(x) = 4x and g(x) = 3x

(fog)(x)

you need take value of g(x), 3x, and put 3x instead of x in f(x) function

(fog)(x)=4*(3x)=12x

answer:

f(x) = 4x and g(x) = 3x

answer:

selling price should be $21 per unit.

step-by-step explanation:

cost price of manual = fixed price + variable cost per package×number of units sold

= 780000+19.85×1250000 = $25592500

now we know learning center wants a profit = $650000

then profit = sale price - cost price

650000=sale price - 25592500

sale price = 650000+25592500 = $26242500

this is the sale price of 1250000 units then selling price per unit should be = total selling price/number of units sold

= $26242500/1250000 =20.994 or $21

selling price should be $21 per unit.
