Answer:
B. 4
Step-by-step explanation:
One small cup is worth $0.25,
One large cup is worth $0.75,
She sold 20 small cups already,
She needs to sell x large cups to make $8.00 in total,
We need to find how many large cups she needs to sell,
Multiply $0.25 by 20 to find how much 20 small cups are worth,
0.25 × 20 = 5
She sold 20 small cups for $5.00,
Now subtract 5 from 8,
8 - 5 = 3
She needs to sell x large cups for $3.00,
Divide 3 by 0.75,
3 ÷ 0.75 = 4
Therefore she must sell 4 large cups in order to make $8.00, option ⇒ B.
