To get free delivery, Alice needs to spend a minimum of $35.00 online at her favorite grocery store. In her cart she has 1.5 pounds of chicken at $6.00 per pound, 1 pack of lettuce for $3.00, cherry tomatoes for $2.50, 4 sweet potatoes at $0.75 each, 2 heads of broccoli for $2.00 each and a pound of Brussel sprouts for $2.50. How much more does she need to spend in order to get free delivery? Think carefully first, then make a decision:
She bought 1.5 pounds of chicken for $6.00 / pound so that's 1.5 * $6 = $9.00. She bought 4 sweet potatoes at $0.75 each so that's 4 * $0.75 = $3.00. She bought 2 heads of broccoli for $2.00 each so that's 2 * $2 = $4.00. The chicken is $9.00, lettuce is $3.00, tomatoes are $2.50, the sweet potatoes are $3.00, broccoli is $4.00 and Brussel sprouts are $2.50 for a total of $9 + $3 + $2.50 + $3 + $4 + $2.5 = $24.00. To get free delivery she needs to spend $35.00, and she already has $24.00 in her cart, so she needs to spend an extra $35 - $24 = $11.00. So, the answer is 11.
