190
$12.75/$0.05 = 255 five cent coins
it's possible only if there are 20 cent coins only for that 7 dollars 1 dollar = 100 cents, 100 cents = 5 of 20 cent coins since you need 5 of 20 cent coins for a dollar, you do 7 times of it. 7 X 5 = 35. Therefore, you need 35 of 20 cent coins for 7 dollars. (or there are 35 of 20 cent coins in 7 dollars)
there are 10 in 1 dollar so 50 in 5 dollars
