Natalie likes to mail lots of postcards when she goes on holiday. In 2014 the cost of a single postcard stamp was 0.34 1. Today Natalie buys 10 postcard stamps so what is the total cost of the stamps

2. Natalie and her freinds decide to buy 100 postcard stamps what will be the total cost of the stamps now?

1: $3.40     2: $34.00

Step-by-step explanation:

you take 0.34 and multiply it by how many stamps you have. So in this case you have 10 stamps for #1 so you move the decimal over to the right once (since one step is a tenth) and you have $3.40 and for 100 stamps you restart with 0.34 and move the decimal over to the right twice since that would be one-hundredths, and you would get 34. or when you add the units $34.00

i not know

y > 1/3x

y < = -x + 4
