Answer:
16 hot dogs
4 chips
Explanation:
Let h = number of hot dogs ordered
Let c = number of chips ordered
Given:
- Total number of orders = 20
- Four times as many hot dogs as chips ordered
⇒ h + c = 20
⇒ h = 4c
Substitute h = 4c into h + c = 20 and solve for c:
⇒ 4c + c = 20
⇒ 5c = 20
⇒ c = 4
Substitute found value for c into h = 4c and solve for h:
⇒ h = 4 × 4
⇒ h = 16
Therefore, 16 hot dogs and 4 chips were ordered.
