Full solution

Q. Gabriela bought a new pair of glasses at the store when they were having a 30% 30 \% off sale.\newlineIf the regular price of the pair of glasses was $72 \$ 72 , how much did Gabriela pay with the discount?\newline$ \$
  1. Calculate Discount Amount: To find out how much Gabriela paid for the glasses, we need to calculate the discount amount and subtract it from the regular price.\newlineFirst, we calculate the discount amount by multiplying the regular price by the discount percentage.\newlineDiscount amount = Regular price ×\times Discount percentage\newlineDiscount amount = $72×30%\$72 \times 30\%
  2. Convert Percentage to Decimal: Now we convert the percentage into a decimal to perform the multiplication.\newline30%30\% as a decimal is 0.300.30.\newlineSo, Discount amount = $72×0.30\$72 \times 0.30
  3. Perform Multiplication for Discount Amount: Next, we perform the multiplication to find the discount amount. Discount amount = $72×0.30=$21.60\$72 \times 0.30 = \$21.60
  4. Subtract Discount Amount from Regular Price: Now we subtract the discount amount from the regular price to find out how much Gabriela paid.\newlinePrice after discount = Regular price - Discount amount\newlinePrice after discount = $72\$72 - $21.60\$21.60
  5. Find Final Price: Finally, we perform the subtraction to find the final price Gabriela paid for the glasses.\newlinePrice after discount = $72$21.60=$50.40\$72 - \$21.60 = \$50.40
