Cheyenne drove 3000 miles in 75 hours. At this rate, how long will it take her to drive 4000 miles?

lyudmila [28]

Set up a proportion:
$\frac{3000}{75}$ = $\frac{4000}{x}$
To solve cross multiply:
3000x=300000
divide both sides by 3000:
3000x/3000=300000/3000
x=100

It will take her 100 hours to drive 4000 miles assuming she continues to travel at this rate.

Aiden is trying to save money and has $1800 to set aside in some type of savings account. He checked his bank one day, and found

kipiarov [429]

I = Prt

Interest on CD = 0.0425 x $1,800 = $76.5
Interest on savings = 0.0275 x $1,800 = $49.5

Difference of interest on CD and Interest on savings = $76.5 - $49.5 = $27

Therefre, he will earn $27 more if he invest in a CD rather than in a savings.
