Question

yuma needs a singer.singer A is offering her Services for an initial $70 in addition to $20 per hour.singer B is offering his services for an initial $140 in addition to $10 per hour.when will the two singers charge the same amount of money?

Answer 1

Since we have the following:

$A\colon p=20h+70$

And:

$B\colon p=10h+140$

Those represent the payment of each musician [A and B], In order to know when they will be paid the same, we proceed as follows:

$20h+70=10h+140$

Then, we solve for h:

$\Rightarrow20h-10h=140-70\Rightarrow10h=70\Rightarrow h=7$

From this, we can tell that after 7 hours of work they both will be paid the same ammount.
