Question 348445: Hi, I have a word problem, actually three of them that I am trying to help my son with. Here is one of them.
Ashton is making a patio in his backyard using paving stones and gravel. He buys 44 stones and gravel that cost $7. If he paid a total of 73 dollars for the stones and the gravel what was the cost of each paving stone?
We are supposed to define the variables, write an equation and solve it. Can you help us please? Thank you, a frustrated mom.

set PerStone$=n
n*44+7$=73$ //PerStone$ multiple NumberOfStones plus Gravel$ equals to Totalcost
n*44=66$ //minus 7 on each side of the equation
n=1.5$ //divide 44 on each side of the equation
PerStoneCost=1.5$
//Recheck
1.5$*44=66$ //PerStone$ mutiple NumberOfStones equals Stones$
66$+7$=73$ //Stones$ plus Gravel$ equals Totalcost
//Answer
The cost of each paving stone is $1.5.
