Answer:
The amount invested at 15% = $257.14
The amount invested at 8% = $942.86
Step-by-step explanation:
Let the amount invested at:
15% = a
8% = b
Total invesment = $1200
Hence:
a + b= $1200....... Equation 1
a = 1200 - b
15% × a + 8% × b = 9.5% × 1200
0.15a + 0.08b = 0.095 × 1200
0.15a + 0.08b = 114..... Equation 2
We substitute 1200 - b for a in Equation 2
0.15(1200 - b) + 0.08b = 114
180 - 0.15b + 0.08b = 114
- 0.15b + 0.08b = 114 - 180
- 0.07b = - 66
b = -66/-0.07
b = $942.85714286
Approximately = $942.86
Note that:a = 1200 - b
a = $1200 - $942.86
a = $257.14
A equals 30 if you read it is going to say that the answer is 30
Total liters of water needed = number of attendee x water consumption/attendee
where
number of attendee = 7000 attendee
water consumption/attendee = 0.5litre of water/attendee
total = 7000 x 0.5 litre
= 3500 litres
computing the water requirement per 200 litre container
water requirement in the event = 3500 litres/200 litre /container
= 17.5 containers
The water requirement in the event at the arena of 7000 attendees is 17.5 containers.
