How much money will Grace save per 100100100 ounces if she purchases the larger bottle

Answer 1

$1.33

Explanation:

Determine the cost per ounce of the larger bottle

cost per ounce = cost of larger bottle / total ounces

$12.99 / 150 = $0.0866

Multiply cost per ounce by 100

$0.0866 x 100 = $8.66

Subtract the above figure from 9.99

9.99 - $8.66 = $1.33
