A) that’s a $.30 decrease so to find the percent you do the formula
3.50x=.30
3.50x/3.50=.30/3.50
X=.0857
.0857=8.57% so$3.20 is 8.57% of $3.50
B) $3.20 markup=18.5% and $3.50 markup is 29.6% but this depends on where you round up at and you get the answer the same way, with the formula $2.70x=.80 because $3.50-$2.70 =.80
Since 19 is a prime number it only goes into 1 and 19 so 1 times 19 is the only possible answer
