### The Two Mangoes Problem

#### Solution:

(1)  If one mango and one banana cost \$4.70, then two bananas and two mangoes cost twice as much:  \$9.40.
(2)  From there we can use the middle bag to find the cost of a single banana:  \$13.00 (2 mangoes and 5 bananas) - \$9.40 (2 mangoes and 2 bananas) = \$3.60 (3 bananas).   If 3 bananas cost \$3.60, then each banana costs \$1.20.
(3)  From the first bag then we can see that a single mango costs \$3.50 (\$4.70-\$1.20), and so the bag of 2 mangoes costs \$7.00.
