O C. 10
OD. 32

Answer 1

B. 4

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.

Answer 2

Connie must sell 4 large cups.

c = 0.25 per/cup

C = 0.75 per/cup

c × 20 = $5

C × 5 = 3.75 ≈ 4

C × 4 = $3

Product of "c" + Product of "C" = $8.00
