Help me please please please

1 ) $17.14

2) $41.8

3) $39.2

4) 12%

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

hi : ) i found this so i hope this !

"we first find value of tax in dollars.

the difference between the two prices   is: 23. 54 - 22 = 1.54

therefore the sales tax in dollars is 1.54

the tax % will be   (amount of tax / original cost price ) × 100

(1.54 / 22) × 100  → (0.07) × 100 =   7

so the tax rate is 7%

we can double check the answer.

7 % of 22   → (7/100) × 22 → 0.07 × 22 = 1.54

22 + 1.54 = 23.54"
