The formula for simple interest is: Total amount = Principal ( loan amount) x (1 + interest rate x time (years).
Using the given information you have:
Total = 7540 x (1 + 0.065 x 2.5)
Total = 7540 x (1 + 0.1625)
Total = 7540 x 1.1625
Total = $8,765.25
12 inch=1 ft
7 x 12=84 inches
84/15=5.6, so he can cut 5 , 15 inch piecs with .6 left over.
Answer:
3 miles
Step-by-step explanation:
This is because 5280 feet in a mile, and 15,840 is triple that amount.
When they work together, it takes John 1/x hours and it takes Brian 1/(x+15) hours to complete 1/4 of the model.
1/x + 1/( x+15 ) = 1/4 / · x ( x+15 )
x+15 + x = x ( x+15 ) /4 / · 4
8 x + 60 = x² + 15 x
x² + 15 x - 8 x - 60 = 0
x² + 7 x - 60 = 0
x² + 12 x - 5 x - 60 = 0
x · ( x + 12 ) - 5 ·( x+ 12 ) = 0
( x + 12 ) · ( x - 5 ) =0
x = - 12 ( not accepted ) or x = 5
The time taken by Brian: 5 + 15 = 20 hours
