15) I'm not positive what this question is asking because there are no directions showing. If you are trying to determine what 57 is to 98 as compared to x out of 100 (finding the percentage out of 100):
57/98=x/100 cross multiply 5700= 98x divide both sides by 98 58.16= x 58.2 rounded= x
***This may not be correct if that is not what the question is asking
16) sale price= subtract original price times the discount from the original price
sale price= $1200 - ($1200 * 10%) sale price= $1200 - ($1200 * 0.10) sale price= $1200 - $120 sale price= $1080 sale price of the bicycle
17) sale price= subtract original price times the discount from the original price
sale price= $5700 - ($5700 * 60%) sale price= $5700 - ($5700 * 0.60) sale price= $5700 - $3420 sale price= $2280 sale price of the car
