Question

sophia is in the market for a new toaster. she finds it in two different stores. the first store sells the toaster for $30 and is having a weekend sale with a 10% discount on all items. the second store sells the toaster for $28, but sophia has a membership card that allows her to get a 15% discount on her purchase. which store offers sophia the better deal?

Explanation:

Step1: Calculate the price at the first store

The first - store sells the toaster for $30 and has a 10% weekend sale. The discount amount is $30\times0.1 = 3$. The price after the discount is $30-(30\times0.1)=30\times(1 - 0.1)=30\times0.9 = 27$.

Step2: Calculate the price at the second store

The second - store sells the toaster for $28. Sophia has a 15% membership - card discount. The discount amount is $28\times0.15 = 4.2$. The price after the discount is $28-(28\times0.15)=28\times(1 - 0.15)=28\times0.85 = 23.8$.

Step3: Compare the prices

Since $23.8<27$, the second store offers a better deal.

Answer:

Sophia can buy the toaster cheaper at the second store.
