Ralph and Jody go to the shop to buy potato chips and candy bars. Ralph buys 3 bags of potato chips and 4 candy bars. He spends

Jody buys 4 bags of potato chips and 2 candy bars. She spends $3.00.

Later Clancy joins Ralph and Jody and asks to buy one bag of potato chips and one candy bar from

them. They need to work out how much he should pay.

Ralph writes

3p+ 4b = 375

1. If p stands for the cost, in cents, of a bag of potato chips and b stands for the cost, in cents, of a

candy bar, what does the 375 in Ralph's equation mean?

What is the solution to the equation 9^(x+1) =27

Last one and the bottom answer choice is y=(x-4)^2+1 you guys!

Use the information given below, to compare the cost of operating two different vehicles for one month (4 weeks) you are considering two different cars. you drive to work, a 20 mile round trip, five days a week. gasoline costs you $1.50 per gallon car agets 28 miles per gallon, would have $300 a year in maintenance costs, and would cost you $1,500 per year to insure car b gets 19 miles per gallon, would have $500 a year in maintenance costs, and would cost you $1,000 per year to insure costs car a car b gas cost per month insurance cost per month maintenance cost per month $ total cost per month
