Answer:
$300 + $200x
Step-by-step explanation:
So to even use the studio you need to pay $300. For every hour you use the studio you have to pay $200 dollars. So the price would end up as $300 + $200x. The variable stands for how many hours Michael uses the studio.
Answer: 13.8
No 2/3 of $21 is $14 so 6x14 is $84 less than $110
