He is incorrect because he multiplied the bases.
Suppose the original price to be x.
62%x=296.4
Divide both sides by 62% to get x=478, which is the original price.
$12.35 because if u cross multiply 120/100 and 14.82/x u can solve algebraically and get 12.35
10% of 35 is 3.5
20%= 7
50% = 17.5
25% = 8.75
10% of 250g is 25
10% of 350 is 35
10% of 205 is 20.5
10% of 305 is 30.5
lemme get the branliest
$12.80 × 1.075 = $13.76
$13.76 × 1.15 =$15.82
