Answer:
she has $78.5
Step-by-step explanation:
1- She has 5 rolls of pennies containing 50 coins each.
Total pennies she has = 5*50 = 250 pennies
Now, we will get the amount of pennies she has in dollars as follows:
1 penny ............> 0.01 dollar
250 pennies .....> ??
Amount is dollars = 250*0.01 = $2.5 .............> I
2- She has 3 rolls of nickels containing 40 coins each
Total nickels = 3*40 = 120 nickels
Now, we will get the amount of nickels she has in dollars as follows:
1 nickel ..............> 0.05 dollar
120 nickels .........> ??
Amount in dollars = 120*0.05 = $6 ............> II
3- She has 6 rolls of dimes containing 50 coins each
Total dimes = 6*50 = 300 dimes
Now, we will get the amount of dimes she has in dollars as follows:
1 dime ...........> 0.1 dollar
300 dimes .....> ??
Amount in dollars = $30 ...............> III
4- She has 4 rolls of quarters containing 40 coins each.
Total quarters = 4*40 = 160 quarters
Now, we will get the amount of quarters she has in dollars as follows:
1 quarter ...........> 0.25 dollar
160 quarters ........> ??
Amount in dollars = $40 ..........> IV
5- Final step:
we will add I,II,III and IV to get the total amount of money she has as follows:
Total amount of money = 2.5 + 6 + 30 + 40
Total amount of money = $78.5
