Question

Five stamps cost $9.50. Write an equation that could help determine the cost of 25 stamps.

Answer 1

So 5 stamps = $9.50 we need to determine the cost of 1 stamp.

Divide 9.50 by 5 & you get 9.50/5 = $1.90 each.

Check answer: 5 x $1.90 = 9.50 so now we can use this on any amount of stamps wanted for purchase. The X value to be fashionable.

$1.90 x (#of stamp needed) = Cost of Stamps$$.

$1.90x 25 = $47.50

Answer 2

Since 5 stamps cost $9.50, and 5 goes into 25 five times, your equation should look like this:

5·9.5=47.5
