The food truck offers catering services, providing different kinds of salads for parties and events. Tammy looks at the paper menu to decide what to buy:

- Macaroni Salad: $5 per pound
- Potato Salad: $8 per pound

Tammy plans to order both macaroni and potato salad. She estimates spending a total of $38 on 7 pounds of salad. She uses this system of equations to determine how many pounds of macaroni salad (m) and potato salad (p) she plans to buy:

1. \(5m + 8p = 38\)
2. \(m + p = 7\)

How many pounds of each salad does Tammy plan to buy?
