1. Jane saved up 20 coins, all nickels and
kompoz [17]

Answer:

10 nickels and 10 quarters

Step-by-step explanation:

Given

Number of coins: 20

Vaiue of coins = $3.00

Required

Number of Nickels and Quarters;

<em>Let N =Nickels and Q =Quarters</em>

The total coins is represented as:

N + Q = 20

1 nickel is equivalent to $0.05 and 1 quarter is equivalent to $0.25; So

0.05N + 0.25Q = 3

Make N the subject of formula in the first equation

N = 20 - Q

Substitute this in the second equation

0.05(20 - Q) + 0.25Q = 3

1 - 0.05Q + 0.25Q = 3

Collect like terms

-0.05Q + 0.25Q = 3 - 1

0.2Q = 2

Multiply both sides by 5

5 * 0.2Q = 2 * 5

Q = 10

Recall that N = 20 - Q

N = 20 - 10

N = 10
