Question

June has $1.95 in dimes and nickels. She has a total of 28 coins. How many of each type of coin does she have?

Answer 1

Answer:

She has 11 dimes and 17 nickels

Step-by-step explanation:

dimes --- d

nickels -- n

Equation with number of coins: $n+d = 28 n = 28-d$

$10d + 5n = 195$

Divide by 5

$2d + n = 39$

sub in the other equation:

$2d + 28-d = 39 d = 11 n = 28-11 = 17$
She has 11 dimes and 17 nickels

check:

total = 11 + 17 = 28 , check!

value: 10(11) = 5(17) = 195 , check!
