I think the answer is -8. I don’t know if the answer’s supposed to be a fraction but I’m pretty sure the answer is -8. If you isolate v you get -1. So now substitute v for -1 (2x-1 -6) and you get -8.

A teacher spends $354 on costumes and microphones for six cast members in a play. Each cast member receives a costume that costs
KATRIN_1 [288]

The teacher spend some amount on buying costumes and microphones for 6 cast members.

<u>GiveN</u><u>:</u>

  • Cost of each costume = $38
  • Cost of each microphone = $c
  • Total money spent = $354

Let's frame the equation. Total money is the total amount spent for 6 cast members.

Money spent on costumes = $38 × 6

Money spent on microphone = $c × 6

<u>Equation:</u>

6 \times 38 + 6 \times c = 354

Taking 6 as common,

6(38 + c) = 354

Dividing 6 from both sides,

\dfrac{6(38 + c)}{6}  =  \dfrac{354}{6}

38 + c = 59

Solving further,

38 + c - 38 = 59 - 38

c = 21

So, the cost of each microphone = <u>$21</u>

The teacher spent this much on each microphone.
