Answer:
SUPPORT: 75% of 100 > 50% 10
REFUTE: 75% of 1 < 50% 6
Step-by-step explanation:
75% of 100 is 75, and 50% of 10 is 5. 75 > 5, and that supports the claim
75% of 1 is 0.75, and 50% of 6 is 3. 0.75 < 3, and that refutes the claim.
Answer:

he bought 70 pencils
therefore $4.50 can buy 30 pencils
so 1 pencils cost $4.50 /30=0.15
