Mary Beth would like to buy a more fuel-efficient vehicle instead of driving her mom's gas-guzzler. Assuming she can find a car
that gets 32 miles per gallon (mpg) and her mom's car gets only 16 mpg, how much will she save if she usually drives about 3,000 miles a year and average price of gas is $3.75 a gallon?
The first part of the second line, she left the -5 there. The correct work and solution should be this: 5(2x-1)-3x=5x+9 <span><span>7x</span>−5</span>=<span><span>5x</span>+<span>9 </span></span>2x-5=9 2x=14 x=7
