The problem gives a distance with a fraction (not a decimal); there is absolutely no reason to convert it to a decimal. In 4 days, Val walks: 4*(2 3/5) miles 4*(13/5) miles [convert to improper fraction] 52/5 miles 10 2/5 miles [convert to mixed number] Compare that to Bill, who runs 10 miles every 4 days. Val runs a greater distance.
--Answer--
1. $85
2. $15
--Explanation--
1. 15% off of 100 just means moving the decimal in 15 over by 2 to the left.
From there, multiply 100 x 0.15.
Then you get 15, so that's how much tax you are paying. Meaning Subtract 15 from 100 to get the price it originally was before tax. 100 - 15 = 85.
2. $15 dollars tax from moving decimal 2 to the left of 15%.
