Answer:

Tanisha's car uses 7 gallons of gas driving 175 miles.

Explanation:

With the information provided, you know that Tanisha can drive about 300 miles between 12-gallon fill-ups and with this you can find the gallons of gas needed to drive 175 miles by writing a proportion using this form: a/b = c/d.

12/300=x/175

This indicates that 12 is to 300 as x is to 175. We write x because we don't know the gallons needed yet. Now, we have to cross products and solve for x to find the answer:

12*175=300x

2100=300x

x=2100/300

x=7

According to this, the answer is that Tanisha's car uses 7 gallons of gas driving 175 miles.
