Let as consider, we need to find the fixed fee.

Given:

Cost of each ticket = $18

Number of tickets = 5

Total cost = $93

To find:

The fixed fee.

Solution:

Let x be the fixed fee..

Cost of 1 ticket = $18

Cost of 5 ticket = $(5 × 18)

                         = $90

Total cost 5 tickets = Fixed fee + Cost of 5 tickets

93=x+90

93-90=x

3=x

Therefore, the fixed fee is $3.

Solutions  

In Matrix we use initially based on systems of linear equations.The matrix method is similar to the method of Elimination as but is a lot cleaner than the elimination method.Solving systems of equations by Matrix Method involves expressing the system of equations in form of a matrix and then reducing that matrix into what is known as Row Echelon Form.<span>

Narelle is environmentally consclous and has fitted
LUCKY_DIMON [66]

Answer:

93.5 mm

Step-by-step explanation:

1. Add all the rainfall readings together to find the total rainfall.

12.48+8.82+27.51+44.73=93.54

2. One decimal place means you'll be rounding 93.54 to the nearest tenth. Round down if the decimal place immediately to the right is less than 5, round up if it is greater than or equal to 5. Since 4 is the value in the hundredths place and 4<5, we are going to round down.

3. The answer is 93.5 mm, don't forget your units.

Hope you found this helpful, have a nice day.
