Since both machines maintain their rate, the number of copies made and the elapsed time are proportional. This means that we can write a proportion like

We know the performance of machine a for 12 minutes, and we want those for 30 minutes: the proportion becomes

Similarly, we have for machine b

So, together, the two machines make

copies.

Step-by-step explanation:
Let x = cost of mango
y = c of apples
<span>8x+3y=18.
3x+5y=14.5 </span>
<span> </span>
<span>24x+9y=54
24x+40y=116
multiplying them with 3 and 8 resectively. </span>
<span>subtract one from the other we get </span>
<span>40y-9y=116-54 </span>
<span>31y=62 </span>
<span>y=2.
cost of apple=2$ per apple
</span><span>8x+3y=18,
8x+3(2)=18.
8x=12. x=12/8=1.5 </span>
<span>cost of mango i= 1.5 $ per mango
hope this helps</span>
