Question

mando collects baseball cards he currently has 24 cards and buys 5 new cards a week how many cards will ma do have in 20 weeks

Answer 1

so Mando currently has 24 cards so let's leave that aside

5 new cards per week

5*20= 100

so he will have 100 new cards after 20 weeks
so add the cards he currently have with the new cards so

100+24= 124
Mando will have 124 after 20 weeks

Answer 2

124 cards. You multiple 5x20 for how many weeks and then add the 24 back on.
