Answer:
(B) $0.50
Explanation:
The total cost is a function of the number of maps sold and the number of books sold. To determine the cost of each, a set of equations have to be solved simultaneously.
Let the cost of a map be m and that of a book be b
12m + 10b = 38
20m + 15b = 60
6m + 5b = 19
4m/3 + b = 4, b = 4 - 4m/3
6m + 20 - 20m/3 = 19
2m/3 = 1
m = 3/2 = 1.50
b = 4 - 4m/3
b = 4 - 2 = 2
The cost of a book is $2 while that of a map is $1.50
Hence a map sell for $0.50 less than a book.
Answer:
The correct answer is option B.
Explanation:
Real GDP is the inflation-adjusted measure of economic growth. It measures the change in output level at a constant price. It measures changes in economic output.
Nominal GDP measures change in output level based on current prices. It is not an inflation-adjusted measure of economic growth.
Real GDP changes with a change in output level. While nominal GDP can change with change in either output level or price. So it is not necessary that a decline in real GDP is accompanied by a decline in nominal GDP.

Answer:
The most he can afford to pay = $25,260.07
Explanation:
The most he can afford to pay is the present value of the $375 per month discounted at the interest rate of return of 6.5% p.a
PV = A× (1- (1+r)^(-n))/r
PV = ?, A- 375, r- 6.5/12= 0.541% n= 12×7 = 84
PV = 375× (1- (1.00541)^(-84) )/0.00541= 25260.071
The most he can afford to pay = $25,260.07
<em>Note: the monthly interest rate needed to be computed by dividing 6.5% by 12 and the number of months in 7 years is 7 × 12 = 84 </em>
