Answer: 20 large drinks and 40 small drinks
Step-by-step explanation:
From the information given:
L= number of large drinks while S = number of small drinks
Cost of L = $5, while Cost of S = $3
Total number of drinks sold is 60 = $220
Equations:
L + S = 60 .........equation 1
5L + 3S = 220 ..........equation 2
S = 60 - L
Substitute S = 60 - L into equation 2
5L + 3 (60 - L) = 220
5L + 180 - 3L = 220
Combine like terms:
5L - 3L = 220 - 180
2L = 40
Divide both sides by 2:
L = 20 Large drinks
Substitute the value of L into equation 1
20 + S = 60
S = 60 - 20
S = 40 small drinks
Thus, there are 20 large drinks and 40 small drinks.
