What you do is multiply the lbs of grapes times the amount per pound - 2.5 x $1.00 = $ ?
Subtract that amount from the $7.00 =
Divide the amount left over by $1.50 (the price of the cherries)
If you are having problems with your math, you REALLY should get someone to help you understand it rather than having someone tell you how to do it.... Good luck! (:

First of all, you need to pick out the key words of the problem. You already have the price of grapes per pound and how much grapes there are. At $1 a pound of grapes and she bought 2 pounds: that makes $2.50. That will be part of your equation. Then you have to add the amount of cherries to 2.50 to add to 7 dollars. You don't know how many pounds of cherries she bought, so you will put 1.50x. Here is what you do:
7 = 1.50x + 2.50
Then you solve it by subtracting 2.50 from 7. You get this:
4.50 = 1.50x
Then you divide 1.50 and 4.50 by 1.50 to cancel out the 1.50 to leave x alone and to get the answer. You get this:
x = 3
Mrs. David bought 3 pounds of cherries.

each pound cost 1 and there were 2.5 lbs.
take 2.5*1=$2.5 This is how much the grapes cost.
Then subtract 2.5 from 7. You get $4.50. This is how much the cherries cost. You then divide 4.50 by 1.50 and you will get how many pounds of cherries.
The answer is three.

[(2.5 lbs) x ($1 /lb)] + [(X lbs) x ($1.50 /lb)] = $7
[$2.5] + [(X lbs) x ($1.50 /lb)] = $7
[(X lbs) x ($1.50 /lb)] = $4.50
X = 3 lbs
