Explanation:
We want to find the cost per case. Therefore we must divide the cost by the number of cases.
cost per case= cost/cases
We know that it costs $159.98 for 6 cases of paper.
cost per case= $159.98/6 cases
Divide.
cost per case= $26.66333333333333/case
Round to the nearest cent or hundredth. The 3 in the thousandth place tells us to leave the 6 in the hundredth place.
cost per case ≈$26.66
It costs about $26.66 per case of paper.

2 - Multiply the decimal by the number you are finding the percentage of. This will be your final answer.
(1) 20% of 80
20 / 100 = 0.20
20% = 0.20
0.20 * 80 = 16
16 is 20% of 80
(2) 55% of 1000
55 / 100 = 0.55
55% = 0.55
0.55 * 1000 = 550
550 is 55% of 1000
