Rooney's company decides to buy some keyboards, mouse cursors and PC Cameras. They have a budget for $1500 to spend on $30 keyboards, $20 mice and $50 cameras. Additionally, the number of the cursors should be equal to that of the keyboards and the keyboards are twice the numbers of cameras. How many of each item should he buy? The only thing I'm struggling with is turning the word problem into linear system of equations. Can someone help me out?​

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
