Answer:
1 ) $17.14
2) $41.8
3) $39.2
4) 12%
Step-by-step explanation:
1-3) 100% is full. subtract the percent off by 100. For example #1 is 25%, we would 100% - 25% = 75%. then multiply the percentage by the price which is $22.85 x 0.75 = $17.14
same for the rest
4) use the formula
Discount = original price - selling price
$399 - $350 = $49
then use the formula
% = discount/original price multiply by 100%
$49/$399 which is 0.1228 then multiply it by 0.100 which is 12%
check your answer by 100 - 12 = 88 then 399*0.88 = 351.12
they round the price so it is $350
