Answer: Option (d) is correct.
Explanation:
Amount paid for candy = $1,500
Items received = 8,500 pieces of candy
Group 1 = 2,500 pieces
Selling price = $0.15 each
sale value = pieces sold × Selling price
= 2,500 × $0.15 each
= $375
Group 2 = 5,500 pieces
Selling price = $0.36 each
sale value = pieces sold × Selling price
= 5,500 × $0.36 each
= $1,980
Group 3 = 500 pieces
Selling price = $0.72 each
sale value = pieces sold × Selling price
= 500 × $0.72 each
= $360
Total sale value = $375 + $1,980 + $360
= $2,715
= 72.92%
Proportion of cost for Group 2 = cost × Percentage of sale in Group 2
= $1,500 × 72.92%
= $1,093.8
= $0.1988
= $0.20(approx)
Answer: The actual rate of the mortgage is 5.27%.
Since we're taking two mortgages for a total of $200,000 for 30 years, we can find the actual rate of the mortgage by finding the weighted average of the two rates. The weights in this case will be the proportion of loan taken at each rate
We have
Rates Weights Rates * Weights
4.15 0.80
9.75 0.20
Total 5.27%
