There are 7 days in a week and she needs apples for 2 weeks so that's 7*2 = <<7*2=14>>14 days
She shares an apple with her dog every day so for 14 days so she needs 1*14 = <<1*14=14>>14 apples
Each apple weighs 1/4 of a pound and she needs 14 apples so that's .25*14 = <<1/4*14=3.5>>3.5 pounds of apples
She needs 3.5 pounds of apples and they are on sale for $2.00 a pound so she will spend 3.5*2 = $<<3.5*2=7.00>>7.00 for apples
