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?

Respuesta :

Since we have the following:

[tex]A\colon p=20h+70[/tex]

And:

[tex]B\colon p=10h+140[/tex]

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:

[tex]20h+70=10h+140[/tex]

Then, we solve for h:

[tex]\Rightarrow20h-10h=140-70\Rightarrow10h=70\Rightarrow h=7[/tex]

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