For this case we propose a system of equations. We have to:
x: Let the variable that represents the number of dimes
y: Let the variable that represents the number of quaters
We know that:
One dime equals 10 cents, $0.10
A quater equals 0.25 cents, $0.25
According to the statement we have:

We multiply the first equation by -0.10:

We have the following equivalent system:

We add the equations:

Approximately 3 quater coins

And two dimes
Answer:
3 quater
2 dimes
What you're doing is just dividing 13/8 to find the decimal (1.625) and then divide that number by 100. 162.5%
your answer is 162.5%
Your equation would be t +25=57 because we don’t know how many necklaces Stacy made so we use T to plug it in and solve
Exponential Function.
Plotting the graph using this table gives the first figure. An exponential function has this kind of graph.
