rosijanka [135]

Answer:

Step-by-step explanation:

So the ratio is 5:4:2

there are 11 parts to this ratio (5+4+2)

the 5 is for the $2, the 4 is for the $1 and the 2 is for the 50 cents

he has 30 of the 50 cents

so you divide 30 by 2 to get one part of this ratio

1 part of this ratio is equal to 15 coins

multiply 15 by 5 to get the number of $2 coins: 75

multiply 15 by 4 to get the number of $1 coins: 60

add all of those parts together

30+60+75 = 165

If he uses a $1 coin to buy the sundae he will have 75 $2 coins and 59 $1 coins left

however, if he uses two 50 cents coins to buy the sundae he will have 75 $2 coins and 60 $1 coins left
