Jordy bought 3 sets of 100 stamps, 2 sets of 20 stamps, 4 sets of 12 stamps, and 1 set of 10 stamps. How many stamps did Jordy buy?

Answer 1

398 stamps

Step-by-step explanation:

`\begin{gathered} \text{3 sets of 100 stamps}=3*100=300\text{ stamps} \\ \text{2 sets of 20 stamps}=2*20=40\text{ stamps} \\ \text{4 sets of 12 stamps}=4*12=48\text{ stamps} \\ \text{1 set of 10 stamps}=1*10=10\text{ stamps} \end{gathered}`

Therefore, the total number of stamps Jordy buys:

`\begin{gathered} =300+40+48+10 \\ =398\text{ stamps} \end{gathered}`
