Ken buys gummy vitamins.  They are usually $15.00 per bottle at his grocery store, but they are currently 20% off.  On top of that, he has 3 $2.00 coupons.  How much will 3 bottles cost?
The vitamins are $15.00 a bottle and are currently 20% off so that’s 15*.20 = $<T>multiply(15, 0.2)=3.0 off
The vitamins are $15.00 and they are $3.00 off so they are now 15.00-3 = $<T>subtract(15.0, 3)=12.0
He has 3 $2.00 coupons so that’s 3*2 = $<T>multiply(3, 2)=6 in coupons
He buys 3 bottles at $12.00 each so that’s 3*12 = $<T>multiply(3, 12)=36
He has $6.00 in coupons so his vitamins will now costs 36-6 = $30.00
