Answer:

24weeks

Step-by-step explanation:

So if she spends 5$ three times a week she spends 15$ a week

She babysits once a week for 40$

That means that she saves 25$ from babystitting each week

As she already has saved 200$, she only lacks 600$ for the purchase

If she stops buying coffee it will instead only take her 15 weeks to buy a new laptop

A truck uses 1 tablespoon of gasoline to drive 125 yards. How many miles can the vehicle travel per gallon?

Alborosie

Answer:

18.18 miles.

Step-by-step explanation:

A truck uses 1 tablespoon of gasoline to drive 125 yards.

Now, 1 gallon of gasoline contains 256 tablespoons of gasoline.

So, the truck uses 1 gallon i.e. 256 tablespoons of gasoline to drive (256 × 125) = 32000 yards.

Now, 1-mile distance contains 1760 yards.

Therefore, the truck uses 1 gallon of gasoline to drive $\frac{32000}{1760} = 18.18$ miles. (Answer)
