10) Sky High sells helicopters. During the current year, 130 helicopters were sold resulting in $840,000 of sales revenue, $260,000 of variable costs, and $350,000 of fixed costs. The number of helicopters that must be sold to achieve $320,000 of operating income is . A) 151 units B) 104 units C) 79 units D) 130 units

A) 151 units

Step-by-step explanation:

We would apply the formula which is expressed as

N = (FC + OP)/[(R - VC)/TU]

Where

N represents the number of helicopters that must be sold.

FC represents the fixed cost

OP represents the operating income required.

R represents revenue

VC represents variable cost

TU represents the total number of units sold.

From the information given

FC = 350000

OP = 320000

R = 840000

VC = 260000

TU = 130

Therefore,

N = (350000 + 320000)/[(840000 - 260000)/130]

N = 670000/4461.54

N = 151 units rounded up to the nearest whole number

it is c, trust i got your back lol

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
