Q. Grace examines two different size bottles of the same laundry detergent. The price for the 100100 -ounce bottle is $9.99 \$ 9.99 and the price for the 150150 -ounce bottle is $12.99 \$ 12.99 . How much money will Grace save per 100100 ounces if she purchases the larger bottle?\newlineChoose 11 answer:\newline(A) $0.01 \$ 0.01 \newline(B) $1.33 \$ 1.33 \newline(C) $2.00 \$ 2.00 \newline(D) $8.66 \$ 8.66
  1. Calculate price per ounce: First, let's find the price per ounce for the 100100-ounce bottle.\newline$9.99/100\$9.99 / 100 ounces = $0.0999\$0.0999 per ounce.
  2. Compare prices: Now, let's find the price per ounce for the 150150-ounce bottle.\newline$12.99/150 ounces=$0.0866 per ounce.\$12.99 / 150 \text{ ounces} = \$0.0866 \text{ per ounce}.
  3. Calculate savings per ounce: Next, we need to compare the savings per ounce.$0.0999\$0.0999 per ounce - $0.0866\$0.0866 per ounce = $0.0133\$0.0133 per ounce saved.
  4. Calculate savings per 100100 ounces: To find out how much she saves per 100100 ounces, we multiply the savings per ounce by 100100.$0.0133\$0.0133 per ounce * 100100 ounces = $1.33\$1.33 saved per 100100 ounces.
