Sally picks 30 seashells on Monday. On Tuesday, she picks half as many seashells as she did on Monday. If she can sell each seashell for $1.20, how much money can she make if she sells all of her seashells?
On Tuesday, Sally picks 30 / 2 = <T>divide(30, 2)=15.0 seashells
In total, Sally picks 30 + 15 = <T>add(30, 15)=45 seashells
The total amount of money Sally can make is 45 * $1.20 = $<T>multiply(45, 1.2)=54.0
