2. decimal fraction = percent/100
so \$x + y percent tax = x (1+ y/100)

Sarah 44 * 1.04
Jack 36*1.06

Sarah tax = 0.04*44
Jack tax = 0.06 *36

4. old 8.50
new 10.00
percent change = 100 * (new percent - old percent) / old percent

= 100 (1.50)/8.50
positive is increase

100% - 25% = 75 % which is 0.75 as a fraction
0.750 * 10 = ???
