Liam and Claire picked and sold oranges to save for their mother's birthday gift. Liam picked 40 oranges and sold them at $2.50 for 2 while Claire picked 30 oranges and sold them at $1.20 each. If all of their oranges were sold, how much are they going to save for their mother's birthday gift?
Liam sold 40/2 = <T>divide(40, 2)=20.0 sets of oranges that cost $2.50 for each set.
So, Liam earned $2.50 x 20 = $<T>multiply(2.5, 20)=50.0
Claire earned $1.20 x 30 = $<T>multiply(1.2, 30)=36.0
Thus, they were able to save $50 + $36 = $<T>add(50, 36)=86 for their mother's birthday gift.
