I would love to understand how to solve this problem: Theo and Tia are buying food for their picnic basket.  They invited two of their friends. They buy individual sandwiches and individual fruit salads. They buy two sodas per person and 3 bags of snacks to share for their friends and themselves. Sandwiches are $5 each.  Fruit salad is $3 each.  Sodas are $2 each.  The snack bags are $4 each.  How much did they spend on the entire contents of their picnic basket?
Can you explain?
