Answer:
We can expect 28 defected cars.
Step-by-step explanation:
Let us assume that the defected cars are "uniformly distributed" in the total set of cars.
Then we can write the proportion 8%2F360 = x%2F1260 for the unknown amount x of defected cars among 1260 cars.
Solving the proportion for x you get
x = 8%2A1260%2F360 = 8%2A3.5 = 28.
.75 because .75 is .25 from 1.0 and .25 from .5
17 = -13 - 8x .....add 13 to both sides
13 + 17 = -8x
30 = -8x...now divide both sides by -8
-30/8 = x...reduce
- 15/4 or -3 3/4 = x <===
Answer:
each bottle of juice costs $2.34
Step-by-step explanation:
2.74+10x=26.14
10x=26.14-2.74
10x=23.40
x=23.40/10
x=2.34
