Question 187044

Let x=amount of gas that needs to be added

Since we are only adding gas, the amount of oil before we add the gas (2/32) is the same as the amount of oil after we add the gas ((2+x)/40), so:

2/32=(2+x)/40=
1/16=(2+x)/40  multiply each side by 80
5=2(2+x);
5=4+2x
2x=1
x=1/2 gal-----------------amount of gas that needs to be added
CK
2/32=2.5/40
1/16=1/16

Hope this helps---ptaylor
