    Well now that you have Part A down, lets look at Part b. as I stated, x is the amount of keychains. So we need to solve for x.

    2.25+5x+9.00 9.00-5=4 5x=4 x=0.8

    2.25 + 5x = 9.00 (subtract 2.25 from each side) 2.25 - 2.25 + 5x = 9.00 - 2.25 (combine like terms) 5x = 6.75 (now divide each side by 5) 5x/5 = 6.75/5 x = 1.35 do you understand ?

    C. Sharon's friend says that each key chain costs the same amount of money that the dolls costs. Is she correct ? Well, we have established that a key chain costs $1.35. We were told that the doll costs $ 2.25. Do they cost the same ? You can answer this one. D. If Sharon had not bought the doll and instead bought a pencil for 90 cents. I am not sure what you are asking.....how much would it cost, or how much change would she get back....lets figure both. .90 + 5(1.35) = new total cost .90 + 6.75 = 7.65 Now if she had $9.00, how much change would she get back ? 9.00 - 7.65 = 1.35 (change back) I am not sure what you were looking for in part D, but I hope I covered it for you.
