coldgirl [10]

Answer:

Explanation:

Break even point=fixed cost/ contribution margin per unit

Units to be sold to get target operating income=(fixed costs+ target operating income)/contribution margin per unit

1. Revenue=10%×1600=$160 per ticket

Contribution per ticket=$100-$42=$58 per ticket.

Fixed cost=$29,500

Break even units:$29,500/$58=508.6 tickets

Units to be sold to get target operating income:(29500+$12000)/$58=715.5 tickets

2. Revenue=10%×1600=$160 per ticket

Contribution per ticket=$100-$35=$65 per ticket.

Fixed cost=$29,500

Break even units:$29,500/$65=453.8 tickets

Units to be sold to get target operatig income:(29500+$12000)/$65=638 tickets

3.

Revenue=$50 per ticket

Contribution per ticket=$50-$35=$15 per ticket.

Fixed cost=$29,500

Break even units:$29,500/$15=1966 tickets

Units to be sold to get target operating income:(29,500+$12,000)/$15=2766 tickets

4.

Revenue:$55(fixed comission fee)+$5(delivery fee)=$60 per ticket

Contribution per ticket=$60-$35=$25 per ticket.

Fixed cost=$29,500

Break even units:$29,500/$25=1180 tickets

Units to be sold to get target operating income:(29,500+$12,000)/$25=1,660 tickets

Rus_ich [418]

Answer:

$1,275,000

Explanation:

The computation of the  contribution margin is shown below:

As we know that

Contribution margin = Sales - variable cost

or

Selling price per unit - variable cost per unit

And, the direct material per unit, direct labor per unit, and the  Variable overhead per unit are variable cost

So, if 50,000 units are sold, the contribution margin per unit is

= 50,000 × ($33 - $1.50 - $2.50 - $3.50)

= $1,275,000

olya-2409 [2.1K]

Answer:

41.49 approx 42 months

Explanation:

To calculate the number of months, we use the formula for loan

p = r(pv) / 1 - (1+r)-n

make n subject of the formula

p ( 1 - ( 1+r) ^-n) = r(pv)

p - p (1+r)^-n = r(pv)

p (1+r)^-n = p-r(pv)

(1+r)^-n = (p-r(pv)) / p

( 1+r)^n = p / (p-r(pv))

n In( 1+r) = In (p / (p-r(pv))

n = In ( p/ ( p - r(pv)) / In ( 1 +r)

n is the number of months, p is the payment per months

pv is the present value of 5000

substitute the values given into the equation

n = (In ( 150 / (150 - ( 0.129 / 12 × 5000)) / ( In ( 1 + ( 0.129 / 12) = 41.49 approx 42 months
