Ashley drove 648 miles in 9 hours. At the same rate, how many miles would she drive in 7 hours?
kvv77 [185]
First, divide 648 by 9. 648/9=72. Now we know that Ashley covers 72 miles in an hour. In order to get the number of miles she covers in 7 hours we must multiply 72 by 7 which equals 504. So Ashley would drive 504 miles in 7 hours.

brianna deposit $680.00 into savings account that pays a simple interest rate of 1.29% how much will she earn after 3 years
nordsb [41]
Here's the equation for one year:
0.0129(680) + 680
But because it is 3 years:
3(0.0129(680)) + 680
0.0387(680) + 680
We can make it simpler:
1.0387(680)
Multiply:
706.316
We can round up:
She will have $706.32, and earn $26.32
