The Martin family's truck gets an average of 25 miles per gallon. Predict how many milrs they can drive using 7 gallons of gas.
Hunter-Best [27]
Okay so on average if they can go 25 miles per gallon that would mean you could just multiply 25 and 7 to get 175. So on average they could go 175 miles on 7 gallons of gas. Keep in mind that the answer can and will change depending on traffic, how fast or slow they are going, and if they are traveling behind a big-rig that moves more air that would normally be putting pressure on the car to push out of the way  but the big-rig helps save gas but it can also waste more gas if they are driving slower then normal.
Sorry for the extra information once I start it's hard to stop. Any way I hope this helps.

What is the percent decrease from 60 to 39?
IrinaK [193]
X - the percent decrease

60-60x=39 \ \ \ |-60 \\&#10;-60x=-21 \ \ \ |\div (-60) \\&#10;x=\frac{-21}{-60} \\ \Downarrow \\ x=\frac{-21}{-60}=\frac{-21 \div (-3)}{-60 \div (-3)}=\frac{7}{20}=\frac{7 \times 5}{20 \times 5}=\frac{35}{100}=35\%

It's a 35% decrease.
