Question

George and Mae both bought a new keyboard and mouse for their computers.

They spent the same amount of money.

George’s mouse costs $38.85 and his keyboard costs $31.15.

Mae’s mouse costs $32.50.

How much did Mae’s keyboard cost?

Worked Solution
George's total = 38.85 + 31.15
= $70

Since they spent the same amount of money:
Mae’s keyboard cost = Total cost –– cost of mouse
= 70 −- 32.50
= $37.50
