(a) System of equations are
[tex]2x+4y=14794\\3x+5y=19892\\[/tex]
(b) The cost of MacBook is $2,799
The cost of iMac is $2,299
Given :
Firm purchased 2MacBook Pro notebooks and 4iMac desktops for a total order price of $14,794
they purchased 3MacBook Pro notebooks and 5 iMac desktops for a total order price of $19,892.
Let x be the cost of MacBook Pro
and y be the cost of iMac
Now frame the equation using given information
2 MacBook +4 iMac= 14794
2x+4y=14794
3 MacBook +5 iMac= 19892
3x+5y=19892
System of equations are
[tex]2x+4y=14794\\3x+5y=19892\\[/tex]
To solve for x and y , Lets solve the second equation for x
[tex]3x+5y=19892\\3x=19892-5y\\x=\frac{19892-5y}{3}[/tex]
Substitute x in first equation and solve for y
[tex]2\cdot \frac{19892-5y}{3}+4y=14794\\\frac{39784+2y}{3}=14794\\\frac{3\left(39784+2y\right)}{3}=14794\cdot \:3\\39784+2y=44382\\2y=4598\\y=2299[/tex]
Substitute y value in the x equation
[tex]\mathrm{\:}x=\frac{19892-5y}{3}\\x=\frac{19892-5\cdot \:2299}{3}\\x=2799[/tex]
The cost of MacBook is $2,799
The cost of iMac is $2,299
