I need help can someone help with this!! Joanne has a pile of nickels and a pile of dimes. She counts her money and discovers that she has 30 nickels and 10 dimes. Let x represent the number of nickels and y represent the number of dimes. (HINT: Use the values of the coins.) How much money does Joanne have in total?

$2.50

Step-by-step explanation:

x=$1.50

y=$1.00

$2.50

Step-by-step explanation:

x is the number of nickels

y is the number of dimes

t is the total amount of money

5x+ 10y = t

   - one nickel = 5 cents, and one dime = 10 cents

insert 30 nickels and 10 dimes

5(30) + 10(10) = t

150 + 100 = t

t = 250 cents

250 * 0.01 to change cents into dollars

250 * 0.01 = 2.50
