The correct answer would be A
Answer:
300 dimes and 120 quarters
Step-by-step explanation:
Let x be the number of dimes and y be the number of quarters Travis has. Travis has $60 (6000 cents) in dimes and quarters, then

If he could switch the numbers of dimes with the number of quarter, he would have y dimes and x quarters. In total this amount of money is $87 (8700 cents), then

Solve the system of two equations:

Multiply the 1st equation by 5, the 2nd equation by 2 and subtract them:

Then

Answer:The interest is: $163.80
Step-by-step explanation: P is the principal amount, $630.00.
r is the interest rate, 6.5% per year, or in decimal form, 6.5/100=0.065.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 630 × 0.065 × 4 to get that:
The interest is: $163.80
Yes hi hello, it is not a linear function. It is a exponential function, because 64 divided by 2 equals 32, and 32 divided by 2 equals 16. The slope goes from -32 to -16. The equation is Y=64•(0.5 to the variable, X, power). (This is Lennox, Andrea’s friend who is smart.)
