Determine the number of minutes (t) that he was on the trampoline.
This can be expressed as:
Where t represents the number of minutes
Substitute values for Total, Entrance Fee and Amount per minute
Solving further to get the value of t, we have:
Answer:
Step-by-step explanation:
The constant increase every hour indicates a linear correlation, which can be represented by an arithmetic sequence.
The nth term formula is a formula for any specific term you wish to find.
The formula is:
a = starting value of the sequence
d = the common difference (i.e. the difference between any two consecutive terms of the sequence)
n = the value corresponding to the position of the desired term in the sequence (i.e. 1 is the first term, 2 is the second, etc.)
Un = the actual vaue of the the term
In this case:
a = 40
d = 10
And so, the nth term formula is:
Answer: Cost of each hot dog and bratwursts would be $1.1 and $1.35 each.
Step-by-step explanation:
Since we have given that
Cost of each dozen hot dogs be 'x'.
Cost of each dozen bratwursts be 'y'.
The first day they sold 8 dozen hot dogs and 13 dozen bratwursts for $316.20.
So, the equation would be
.The second day they sold 10 dozen hot dogs and 15 dozen bratwursts for a total of $375.00.
So, the equation would be
So, the equations becomes
So, by elimination method, we get that
Put the value of y in the eq(1), we get that
Hence, the cost of hot dogs would be
And the cost of bratwursts would be
