Answer:
£4.50
Step-by-step explanation:
She is at the car park for 2 hours and 30 minutes.
It would be £4.50 because 2 hours and 30 minutes is between 2-4 hours.
It can't be £3.00 because it would be too little time (2 hours or less) and it wouldn't be £5.50 because she would be paying for more time than she was there for (5 hours or more).
Hope this helps :)
Answer:
The expressions for the payment made to Mary are,
(Monday) 90 = 15m + b
(Tuesday) 62 = 8m + b
where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.
The equation that represents Mary's earning is
y = 4x + 30
For 20 students,
y = 4(20) + 30 = 110
For Lisa's earnings,
y = 8x + 15
Substituting 20,
y =8(20) + 15 = 175
Thus, Lisa would earn more than Mary by $65.

Step-by-step explanation:
Given
The question has missing details; as what's required is not stated.
However, since it is a linear equation, possible questions could be
1. Determine the slope
2. Determine the D-intercept
3. Calculate the amount in dollars for (say) 5 miles
An equation is represented as:
Where
By comparing: to
and 
This means that the slope is 0.3 and the d intercept is 25
To get the amount for 5 miles, we substitute 5 for x in
<em>The cost of 5 miles is $26</em>
Make use of the above explanation to solve the question
5y - 3 = 3y + 27
2y = 30
y = 15
m<A= 5(15) - 3 = 75 - 3 = 72
m<B = [360 - 2(72)]/2
m<B = [360 - 144] / 2
m<B = 216 / 2
m<B = 108
