60
Step-by-step explanation:
50+50+50+50+100= 300
divide by 5 students
300/5 = 60
In order for Andrea to make profit, the value of the C in the given function must not be 0 or less than zero. So, let's find the value of x when C is zero.
C = 0 = 10x - 50
x = 5
Hence, the number of candles sold represented by x must be more than 5 (< 5). Therefore, the domain is (5,+∞). When the value of x is more than 5, the C or the range would be greater than 0. Thus, the range is (0,+∞).
The cost of the path around the swimming pool with length 15m and width 12m is $1,190
<h3>Area of a rectangle</h3>
Pathway with 2m wide:
- Length = 15m + 2m = 17m
- Width = 12m + 2m = 14m
Area of the path = length × width
= 17m × 14m
= 238 square meters
- Cost of the path = $5 per square meter
Total cost of the path = 238 square meters × $5
= $1,190
