Lets do this like this:
X = number of quarters and y=number of dimes.
Now, we know that the total number is 35 and that the change adds up to 6.50.
One equation we can form is <span>x+y=35</span>Remember the total number of coins is 35.
The other equation is <span>25x+.1y=6.5</span>Because the number of dimes times their value plus the number of quarters times their value gives us a total of 6.5. Now we can solve for x or y easily in the first equation.
Solving for y like this:<span>y=35−x</span>We can substitute this into the other equation to obtain<span>.25x+.1(35−x)=6.5</span>This simplifies to<span>.15x+3.5=6.5</span><span>.15x=3</span><span>x=<span>20
I hope this can help you indeed</span></span>

Answer: Carson's average points in each game = 122
Jana's average points in each game = 104.4
Step-by-step explanation:
By the given table,
1) The total points Carson get in the game = 366,
He played games = 3,
⇒ His average point in each game = Total points he get/ total game he play
= 366/3
= 122
2) Now, The total points Jana get in the game = 522,
She played games = 5,
⇒ Her average point in each game = Total points she get/ total game she play
= 522/5
= 104.4
27 : 3 = 9
32 :4 =8 (patrimea)
9+8 = 17
