George charged a motorized bicycle on his credit card for $2,000 on June 12. His balance before that purchase on that credit car
Gnesinka [82]
The calculation uses the accumulated daily balance method (ADB).
We assume the statement is based on calendar month (rare!).

George owes $500 from beginning to end of June, so 30 days out of 30.
Interest accrued is 500*0.013*30/30=$6.50.
He also owes $2000 from June 12 to June 30, so 19 days inclusively.
Interest accrued is $2000*.013*(19/30)=16.47
Total interest at the end of the month=$6.50+$16.47=$22.97

20. Two employees of a company have to file expense reports for their travel. The first had taken 7 trips with a mean trip cost
astra-53 [7]

Answer:

What is the mean cost of all 12 trips?

$937.50 per trip

What was done wrong in the proposed solution?

In order for this solution to be correct, both employees should have taken the same number of trips since the weight per trip is equal for both of them. But in reality, the first employee took 2 more trips than the second employee, therefore, the weight of the first employee's trips should be higher. E.g. if both employees had taken 6 trips each, then the average cost per trip would have been $975.

Step-by-step explanation:

the mean cost of all 12 trips = [(7 x $750) + (5 x $1,200)] / (7 + 5) = ($5,250 + $6,000) / 12 = $11,250 / 12 = $937.50

Alchen [17]

3 x 1.8 = 5.4 (m2)

20 cm = 0.2 m

0.2 x 0.2 = 0.04 (m2)

5.4 / 0.04 = 135 (tiles)
