This Is Hard!!! Jerome bought 2 postcards and received $1.35 in change in quarters and dimes. If he.got 6 coins back, how many of each coin did he get?
ok, so we can trial and error
we got quarters, nickles, dimes, pennies,
let's try to max out each one
if we got 5 quarters, then we would have 1 coin left to be a dime to get 1.35
wow, I just guessed
ok, so if we got 4 quarters, then we need 35 cents more with 2 coins, we can't do that because max we can do is 20 cents (2 dimes)
if we got 3 quarers, then we need 60 cents with 3 coins, also impossible since the max we can get with remaining coins is 30 cents (3 dimes)
if we got 2 then we need even more
answer is 5 quarters and 1 dime
