a x 7 = b
500
Write an expression and then solve: Jimmy has $35. He wants to buy 4 cookies at $3 each. How much money will he have left over?
35 - (4 x 3); $23
500
Find the value of the expression. (12 + 8) ÷ 4
(12 + 8) ÷ 4 = 5
500
Write an equation and then solve. Mary had some change in her pocket. She found 3 dimes and a nickel on the sidewalk and now has 90 cents. How much change did Mary have to begin with? (Hint: Work backward to solve!)
c + (3 x 10) + (1 x 5) = 90; c = 55, so Mary began with 55 cents.
