15 = ½ (7x-6)
distribute ½ into parentheses
15 = ½(7x) - ½(6)
15 = ⁷/₂x - 3
multiply by 2
30 = 7x -6
subtract +6 to both side
30 + 6 = 7x
36 = 7x
devide 7 to both side
36
------ = x
7

Conversion of grams to ounces. </h3>
The first step is to convert grams to ounces.
1 gram = 0.035274 ounces
142 grams x 0.035274 = 5.0 ounces
<h3>Mass of the new package</h3>
The new package would be 20% more than the old package. The total mass of the new package in percentage terms is 120%(100 + 20%).
120% x 5 ounces = 6.01 ounces.
<h3>New price </h3>
$0.64 + (0.03 x 6.01) =
$0.64 + 0.18
= $0.82
