To find the total number of cans offered at the given price, we need to the number of cans in a pack by the number of packs. Let's do it!
Shop Smart:& 24 * 2 = 48
Super Saver:& 12 * 4 = 48
Price Busters:& 12 * 3 = 36
Before we find the unit prices, we need to find the that compare the price at each store to the number of cans in the deal. We can do this by the price by the number of cans offered at each store. Then we will divide both the and the of each rate by the value in the denominator. Let's do it!
