A. $2.10
B. $11.90
C. $4.20
D. $42.00

Asked by mjchey

Answer (3)

5 stamps will cost $$2.10
if twenty stamps cost 8.40, we want to find out how many five stamps cost.
20 ÷ 5 = 4
we can use this to calculate ->
8.40 ÷ 4 = 2.10, which is the price for those five stamps :)

20x=8.40 x=0.42
5 stamps or 5x 5x 5(0.42) =2.1$

The cost to buy 5 stamps is $2.10. This is calculated by first finding the cost of one stamp, which is $0.42, and then multiplying it by 5. Therefore, the answer choice is A. $2.10.
