Sam paid $8.28 for 18 stamps.at this rate,how much would it cost Sam to buy 12 stamps

allsm [11]

Answer: It costs $5.52 to Sam to buy 12 stamps.

Step-by-step explanation:

Given: Sam paid $8.28 for 18 stamps.

Thus, the cost of 18 stamps = $8.28

Then the cost of 1 stamp= $\frac{8.28}{18}$

Thus, the cost of 1 stamp=$0.46

With the same rate , the cost of 12 stamps= $0.46\times12$

Therefore, the cost of 12 stamps= $5.52

hence, it costs $5.52 to Sam to buy 12 stamps.
