Answer:
Step-by-step explanation:
Let c represent the number of children that attended the concert.
Let a represent the number of adults that attended the concert.
At one of the concerts, each adult brought 4 children with them, and 10 children attended without an adult. This means that the number of children that attended is
c = 4a + 10
Tickets for a concert were $5 for each child and $8 for each adult. The total ticket sales were $1730. It means that
5c + 8a = 1730
Therefore, the systems of equations that can be solved to determine the number of children, c, and adults that attended the concert is
c = 4a + 10
5c + 8a = 1730
Answer:
1.627 miles
Step-by-step explanation:
longest distance - 2.55 miles
shortest distance - 0.923 miles
difference = 2.55-0.923
=1.627 miles
6 x 3 is 18. y is equal to 4. 18 minus 4 is 14. The answer is 14.
Answer:
The rate of simple interest is 25.89 %
Step-by-step explanation:
Given as :
The principal = $2350
The Amount = $2500
The time period = 90 days = 
year = 0.2465 year
Let The rate of interest = R %
So, Interest = Amount - Principal
Or, Interest = $2500 - $2350 = $150
<u>From Simple Interest method </u>
Simple Interest = 
Or, $150 = 
or, $150 × 100 = $579.275 × Rate
So, Rate = 
∴ Rate = 25.89 %
Hence The rate of simple interest is 25.89 % Answer
