2 Estimating at the Grocery Store O nce Lamar gets to the grocery store, he decides he’d like to make a fruit salad too. He picks up some bananas and strawberries. And the peppers look good to him as well; he wants to include them in the tossed salad. But he’s not sure he’ll have enough money. The bananas cost 79 cents, the strawberries cost $3.89, and the peppers cost 33 cents each. He doesn’t have a calculator with him to add up the amounts like you just did, and it’s too many numbers for him to do in his head. So how can Lamar avoid a nasty surprise when he gets to the checkout counter? He doesn’t want to wait in line only to find out that he doesn’t have enough money with him to pay for his groceries! Estimating in your head is the way to have a good idea how much you are spending on gro- ceries. You do that by rounding up to nearest dollar amount. Fill out the chart on the next page. The first two entries have been done for you. When you’re done, you’ll be able to see whether Lamar can afford to buy the additional groceries.
