Which is cheaper, a \( \$ 180 \) camera discounted by \( 20 \% \) or a \( \$ 155 \) camera discounted by \( 10 \% \) ?

To find out which camera is cheaper after applying the discounts, we can calculate the sale prices. For the \( \$ 180 \) camera discounted by \( 20\% \): - Calculate the discount: \( 20\% \) of \( 180 \) is \( 0.20 \times 180 = 36 \). - Subtract the discount from the original price: \( 180 - 36 = 144 \). For the \( \$ 155 \) camera discounted by \( 10\% \): - Calculate the discount: \( 10\% \) of \( 155 \) is \( 0.10 \times 155 = 15.5 \). - Subtract the discount from the original price: \( 155 - 15.5 = 139.5 \). Now, comparing the two prices: - The \( 180 \) camera is \( 144 \). - The \( 155 \) camera is \( 139.5 \). The \( \$ 155 \) camera discounted by \( 10\% \) is cheaper at \( \$ 139.5 \).
