jennithemeani · Answer

x is the number of boxes he buys

jennithemeani · Answer

so replace x with 6 and make the equation y=9(6)

jennithemeani · Answer

Multiply 9 times 6 and get 54 this the price of 6 of the cheap cereal boxes

jennithemeani · Answer

Then multiply 11 and 6 to see how much the expensive ones cost and subtract to find the difference
66-54=12
He will save $12
