Answer:
$80 + $32x = y
Step-by-step explanation:
80 dollars is mandatory, and will always be charged no matter how many hours the electrician works. The $32 is charged based on how many hours the electrician worked. We don't know how many hours he worked, therefore we put an X next to $32 as a way to remind ourselves to multiply the amount of hours he worked times how much he charges per hour. Y would be the total fee.
Answer:
3 + 1.2 c > 13.50
Step-by-step explanation:
First of all, lets write an equation that gives us the income Janie gets for doing chores. As she earns 1.20 (I will omit the $ symbol for simplicity) for each chore c she makes we can write income depending on the amount of choes as:
income(c) = 1.2 c
If she does 1 chore she gets 1.2, if she does 4 chores she gets 4.8 and so on for any c (obviously c is positive as she can do negative chores).
So, her total money will be the sum of what she earns for chores and the money she already has: 3.
money (c) = 3 + 1.2 c
If she does 2 chores she has 3+2.4=5.4 and so on for any c.
Now we need her money to be greater or equal to 13.50 in order to buy the CD. The inequality is:
money (c) > 13.50
3 + 1.2 c > 13.50
We can go further and solve it. First lets subtract 3 in both sides:
12 c > 10.50
Now, divide both sides by 1.2:
c > 10.50 / 1.2
c > 8.75
So, she needs at least 8.75 chores to earn enough money to buy the CD. As she can do fractions of chores the answer is 8.75 chores. Is she couldn't do fractions she would need at least 9 chores.
Based on the dimensions of the basketball court, we can calculate that the area of the scaled copy is<u> 18 ²³/₆₄ feet².</u>
<h3>Dimensions of scaled copy</h3>
Every 16 feet of the actual court is 1 foot on the scaled copy. The dimensions of the scaled copy are therefore:
= 94 / 16 = 50 / 16
= 5.875 feet = 3.125 feet
<h3>Area of scaled copy </h3>
= Length x Width
= 5.875 x 3.125
= 18.359375
= 18 ²³/₆₄ feet²
In conclusion, the area is 18 ²³/₆₄ feet².
