darkknight · Answer

$.25 per movie ticket and $2 for each book. If she purchased 4 movie tickets she makes $1 off movie tickets. You can write an equation $1 (amount made via movie tickets) + 2$ b ($2 per book) = $17. You need to then solve the equation (1+2b=17) and solve for b to determine how many books Molly purchased last month.
