Travis has $60 in dimes and quarters.If he could switch the numbers of dimes with the number of quarter, he would have $87. How

IgorC [24]

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

$10x+25y=6000.$

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

$10y+25x=8700.$

Solve the system of two equations:

$\left\{\begin{array}{l}10x+25y=6000\\ \\10y+25x=8700\end{array}\right.\Rightarrow \left\{\begin{array}{l}2x+5y=1200\\ \\2y+5x=1740\end{array}\right..$
