Answer:
$3
Step-by-step explanation:
Whenever some type of expenditure is made, there are usually 2 types of costs available: the fixed cost and the variable cost. Former is the constant cost which has to be incurred in order to gain the advantage from the expense. Latter is the cost that varies with the duration of the expense. Therefore, total costs (TC) = fixed costs (FC) + variable costs (VC). VC can be expressed as: VC = price per hour (p) * number of hours (h). So the equation becomes TC = FC + p*h. In this question, FC = $43, TC = $64, h = 7 hours, and p is unknown. So plugging in the values give:
64 = 43 + 7p.
Solving the equation for p gives:
p = 21/7. This implies that p = 3.
Therefore, the hourly fee is $3!!!
Answer:
not sure
Step-by-step explanation:
A credit card's interest rate is the price one pay for borrowing money. This is called the annual percentage rate (APR).The Interest paid can be calculated by the formula I=PTR ÷ 100
Where P = Principal amount ,R= rate of interest in years.T= time.
P=$1,300 ,R= 20% T= year.
Substituting these values :
I= 1300 x 20 x1 ÷100
I= 260. He will pay an interest of 260÷12= $21.7 per month.
Given :-
- 12 workers can do a piece of work in 20 days .
To Find :-
- How many workers should be added to complete the work in 16 days ?
Solution :-
According to the question ,
→ In 20days 12 workers can do a piece of work.
→ In 1day 12*20 workers can do that work
( Less days , more workers )
→ In 16 days 12*20/16 = 15 workers can do the work.
So 15 -12 = 3 workers should be added to complete the work.
