Me make a word problem for water bottles. (see picture below)

1. "Kevin has a 15% off coupon for buying water bottles at Walmart.

One water bottle is usually $2.00. How much did Kevin pay with his coupon?"

2. $1.70.

3. The answer is $1.70, because $2.00 * 0.15 = 30 cents, which is how much the coupon is worth. The sale price is the original amount minus the coupon's monetary value (which is $2.00 - $0.30 = $1.70).

4. I'll leave that part to you lol

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
