The vitamins are $15.00 a bottle and are currently 20% off so that’s 15 * .20 = $3.00 off. The vitamins are $15.00 and they are $3.00 off so they are now 15.00 - 3 = $12.00. He has 3 $2.00 coupons so that’s 3 * 2 = $6.00 in coupons. He buys 3 bottles at $12.00 each so that’s 3 * 12 = $36.00. He has $6.00 in coupons so his vitamins will now costs 36 - 6 = $30.00.
Therefore, the answer is 30.
