Answer:

$2.5

Explanation:

Given:

Number of sandwiches in basket = 20

Number of magazines in basket = 30

cost of sandwiches in 2006 = $4

Cost of magazines in 2006 = $2

cost of sandwiches in 2007 = $5

Consumer price index in 2007 = 125

Now,

Consumer price index = \frac{\sum(p_1q0)}{\sum(p_0q0)}\times100

or

125 = \frac{20\times\$5+30\times X}{20\times\$4+30\times\$2}\times100

here,

X is the price of magazines in 2007

thus,

125 = \frac{\$100+30\times X}{$80+$60}\times100

or

1.25 × ($80 + $60 ) = $100 + 30X

or

30X = $175 - $100

or

X = $2.5

Hence,

The price of magazines in 2007 was $2.5

Answer:

Machine B EAC is $17,705.78 more than Machine A EAC.

Explanation:

First find the present values of the cost of both machines.

Machine A:

= 200,000 + (15,000 * Present value of annuity interest factor, 15%, 8 years)

= 200,000 + ( 15,000 * 4.4873)

= $‭267,309.5‬0

Machine B

= 300,000 + (17,500 * Present value of annuity interest factor, 15%, 10 years)

= 300,000 + 17,500 * 5.0188

= $‭387,829‬

Equivalent Annual cost Machine A:

= [(NPV * Required return) / 1 - (1 + Required return) ^–Number of Periods

=[(267,309.50 * 15%) / 1 - 1.15⁻⁸

= $59,569.95

Equivalent Annual cost Machine B:

= (387,829 * 15%) / (1 - 1.15⁻¹⁰)

= $77,275.73

Difference:

= 77,275.73 - 59,569.95

= $‭17,705.78‬

Answer:

$127,400

Explanation:

Gross profit ratio = [(sale - cost) ÷ sale price] × 100

                           = [($5,000,000 - $3,700,000) ÷ $5,000,000] × 100

                          = 0.26 × 100

                          = 26%.

Gross profit on down payment is recognized in 2019:

= Down payment × Gross profit ratio

= $490,000 × 26%

= $127,400
