Charlotte’s ice skates cost $30.45 less than her skateboard. Her ice skates cost $95.28. How much did her skateboard cost? Write and solve a subtraction equation. Max solved the problem: b = the cost of the skateboard b - 30.45 = 95.28 - 30.45 - 30.45 b = $64.83 Do you agree with Max's mathematical thinking?
