Answer this question: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 = $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.
The answer is 30.

Answer this question:Marcel goes to the store with Dale to buy groceries for cooking dinner. Marcel buys 10 ears of corn, and Dale buys half that amount. Dale buys 8 potatoes and Marcel buys some, too. If they check out together and end up buying 27 vegetables, how many potatoes did Marcel buy?
Marcel bought 10 ears of corn and Dale bought 1 / 2 what Marcel did, 10 x 1 / 2 = 10 / 2 = 5 ears of corn that Dale bought. Together, Marcel and Dale bought 10 + 5 = 15 ears of corn, or 15 vegetables. They end up buying 27 vegetables total, and from those 27, 15 of them were corn. The rest of the vegetables are potatoes, 27 vegetables - 15 ears of corn = 12 potatoes. Dale bought 8 potatoes, so Marcel bought 12 - 8 = 4 potatoes.
The answer is 4.
