ELEN [110]

Answer:

B) 7/9

Step-by-step explanation:

<h3>Fraction addition:</h3>
  • If the denominators are not same, find the LCM of the denominators.

                 \sf =\dfrac{7}{9}

pshichka [43]

Answer:

Step-by-step explanation:

Given:

Cost of L = $5

Cost of S = $3

No. of drinks sold = 60 drinks

Total sale = $220

Solution:

L + S = 60 - (1) (multiplying by 3)

5L + 3S = 220 - (2)

(-)3L +(-) 3S = (-)180 - (1)

2L = 40

L = 40 / 2

L = 20 Large drinks

20 + S = 60

S = 60 - 20

S = 40 small drinks

Therefore, 20 large drinks and 40 small drinks
