Grandma and Grandpa need help figuring how much gas they need to get back home from the beach.
Hello, can you help us determine the amount money we will spend on gas that we need to get back home?
One gallon of gas cost $2 and we want to know how much we will be spending on gas. We also stopped by the store to pick cookies.
The packs of cookies cost $13. So the equation is 2x+13=33
First we need to subtract 13 from 13 and 33 to cancel it out then we have 2x=20 we have to divide 20 by 2 which equals 10.
So if we bought 10 gallons and each gallon cost $2 then 10 x 2 equals $20 so we need $20 to get back home.
I'm definitely not paying for that gas
Thank you for helping us!
