Question

3. Chan Hee is paid $25 for tutoring.

Then he spends $4 on a sandwich
and $2 on a drink. Write an
equation to show the amount of
money Chan Hee has now. Solve
the equation.

Answer 1

Answer: x + 2 + 4 = 25

x = 19

Explanation:

First, you would solve The word problem with the equation 25 - 2 - 4, which equals 19, then you essentially flip the equation around, but instead of 19, you have x. when you do this it’s important to flip the operation you use too, so if the original equation uses subtraction, switch it to addition, and vise versa. The end result would be x + 2 + 4 = 25.
