Answer:

See explanation

Step-by-step explanation:

Step 1. Substitute for d to solve for n:

From the first equation:

$d=70-n$

Then substitute it into the second equation:

$0.1(70-n)+0.05n=5.5\\ \\7-0.1n+0.05n=5.5\\ \\7+(-0.05n)=5.5\\ \\-0.05n=5.5-7=-1.5\\ \\n=\dfrac{-1.5}{-0.05}=30$

Step 2: Substitute for n to solve for d:

$d+n=70\\ \\d+30=70\\ \\d=70-30=40$

To charter a fishing boat for 3 hours the captain charges a base fee of 45.00 plus 15.00 per person using variables construct a

steposvetlana [31]

Answer:

$90.00

Step-by-step explanation:

Given

$c = 45.00$ --- base fee

$m = 15.00$ --- rate

$x = 3$ --- individuals

Required

Determine the total amount paid (y)

The relationship between the variables is:

$Total = Base\ Fee + Rate * Individuals$

$y = c + mx$

This gives:

$y = 45.00 + 15.00 * 3$

$y = 45.00 + 45.00$

$y = 90.00$

Hence, the amount is $90.00
