Answer:
$86.8
Step-by-step explanation:
Given that,
Principal, P = $80
Rate of interest, R = 8.5%
We need to find the money he will have in 1 year. As the interest is not compounded, it must be simple interest. The simple interest can be calculated by the formula,

We know that,
Amount = Principal + interest
= $80 + $6.8
= $86.8
Hence, the amount will become $86.8.
Answer:
Step-by-step explanation:
Set up a proportion
693 miles / 11 hours = 315 miles / x hours
Notice that the numerators both have the same units (miles).
Cross multiply
693x = 11 * 315 Combine
693x = 3465 Divide by 693
x = 5
It will take him 5 hours to go 315 miles
You multiply 2(x+1) which is 2x+2.
Then you multiply 5(2x-3) which is 10x-15
Finally, you add 2x+2 and 10x-15, and you get 12x-13
The answer is 12x - 13
Hope this helps!
