Jude has 30 coins of quarters and nickels. The total amount he has is $5.10. How many of each coin does Jude have? Write the system. Write the equations in the order that they appear in the problem.

Required system

x+y= 30

0.25x+0.05y=5.10

Jude has 18 quarters and 12 nickels.

Step-by-step explanation:

Let x= Number of quarters

y= Number of nickels

As per given,

x+y= 30   (i)

0.25x+0.05y=5.10  (ii)   [1 quarter = $0.25 , 1 nickel = $0.05]

Multiply 0.25 on both sides of equation (i)

0.25x+0.25y= 7.5   (iii)

Eliminate (ii) from (iii) , we get

0.20y=2.4

⇒ y = 12  [divide both sides by 0.20]

Put value of y in (i\), we get

x+12=30

⇒ x= 30-12= 18

Hence, Jude has 18 quarters and 12 nickels.

its c or d   take a lucky guess my dude
