Final answer:

To determine the better deal for the laptop, we calculate the sale prices after discounts at both stores. Save-a-lot has the lower sale price of $143 compared to Save-Even-More's $150, making Save-a-lot the better option.

Step-by-step explanation:

To determine which store offers the better buy for the laptop, we need to calculate the discounted price at both stores and compare them. For Save-a-lot, the laptop is $220 with a 35% discount. We can find the amount of discount in dollars by multiplying the original price by the discount rate in decimal form. Then we subtract the discount from the original price to get the sale price.

Save-a-lot Calculation:

  1. Original price: $220
  2. Discount rate: 35% (which is 0.35 in decimal form)
  3. Discount amount: $220 * 0.35 = $77
  4. Sale price: $220 - $77 = $143

For Save-Even-More, the laptop is $250 with a 40% discount. Using the same method:

  1. Original price: $250
  2. Discount rate: 40% (which is 0.40 in decimal form)
  3. Discount amount: $250 * 0.40 = $100
  4. Sale price: $250 - $100 = $150

Comparing the sale prices, it's clear that Save-a-lot's price of $143 is lower than Save-Even-More's price of $150, meaning Save-a-lot offers the better deal for the laptop.
