Jolene wants to raise some money to buy a bicycle.  She babysits for 4 families for $30 each.  She also washes 5 neighbors’ cars for $12 each.  How much did she raise so far?
For babysitting, Jolene raises 4 x $30 = $<T>multiply(4, 30)=120
For car washing, she raises 5 x $12 = $<T>multiply(5, 12)=60
So far, she has raised $120 + $60 = $<T>add(120, 60)=180
