The number of dime Jenna have is 15 and the number of quarter Jenna have is 35.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Every evening Jenna empties her pocket and puts pockets and puts her change in a jar.
At the end of the week, she counted her money.
One week she had 50 coins all of them were dimes and quarters.
When she added them up she had a total of $10.25.
Let d be the number of dimes and q be the number of quarters.
Dimes = $ 0.10
Quarter = $ 0.25
Then the equation will be
d + q = 50 ...1
0.10d + 0.25q = 10.25 ...2
By solving equations 1 and 2, we have
d = 15 and y = 35
Then the number of dime Jenna have is 15.
