Baron wanted to buy pokemon cards. Having $20 on him, he was wondering how many packs of pokemon cards(1 packet has 7 cards) he can buy if each packet of cards cost $5. Furthermore, he also wants to know if he has enough cards to form a deck (40 cards in a deck) a) what is the maximum number of packets of cards he can buy? b) does he have enough cards to form a deck?

a) $$$20/$5 = 4$$ Maximum number = 4 b) $$4*7=28$$ He would only be able to get a maximum of 28 cards. So it is not possible for him to form a deck of 40 cards.

Allan is interested in the whole trend of cryptocurrency, so he went to buy 30 Alge Coins for 20 cents a coin in the year 2020. Exactly after a year or so, he took a look at the current Alge coin prices and realised that an Alge coin is now worth 30 cents. a) Express an algebra equation for how much his coins are worth now. b) How much did he made from investing in Alge coins.

a) Let's take Alge coins as A Price per coin in 2020 as P Price per coin in 2021 as Q Total amount in 2020 as x Total amount in 2021 as y in 2020: P = 0.20 Q = 0.30 30A*0.2=x 30A*0.3=y x= $6.00 y= $9.00 b) How much he made: y - x = 9 - 6 = $3.00
