At Sweet Stuff Fresh Produce the price of a bag of
grapes depends on the total number of bags purchased
at 1 time, as shown in the table below. In 2 trips to
Sweet Stuff this week, Janelle purchased 3 bags of
grapes on Monday and 4 bags of grapes on Wednesday.
How much money would Janelle have saved if she had
instead purchased 7 bags of grapes in 1 trip on
Monday?
