In November, a toy was $40.00. In Dec., the price increased by 80%. In Jan., the price decreased by 80%. What was the price of the toy after it was discounted in January?
November=$40.00
December=40.00+80%(32)=$72.00
January=72.00-80%(57.60)=$14.40
November = $40.00
December = 40.00+80%(40) = 40 + 32 = $72.00
January=72.00-80%(72) = 72 - 57.60 = $14.40
The work was correct, but the notation might have been confusing.
To find the price of the toy after the discount in January, we need to calculate the final price by applying the given percentage changes step by step.
First, let's calculate the price increase in December. The price increased by 80%, which means it increased by 80% of $40.00.
Price increase in December = 80% × $40.00
Price increase in December = $32.00
The new price after the increase in December can be found by adding the increase to the original price.
New price in December = $40.00 + $32.00
New price in December = $72.00
Now, we have to calculate the price decrease in January. The price decreased by 80%, which means it decreased by 80% of $72.00.
Price decrease in January = 80% × $72.00
Price decrease in January = $57.60
To find the final price after the discount, we subtract the decrease amount from the price in December.
Final price after discount in January = $72.00 - $57.60
Final price after discount in January = $14.40
Therefore, the price of the toy after it was discounted in January is $14.40.
