To make this easier we can convert the fractions to whole numbers and then back.
Lets have 100 represent the can.
1/4 = .25 so we will convert it to 25
100 - 25 = 75
1/5 of 75 is 15
75 - 15 = 60
60/100 = 6/10 = 3/5
The possible coordinates of the point G on the number line as described in the task content are; 5 or -3.
<h3>What are the possible coordinates of point G?</h3>
It follows from the task content that the distance between points E and G as given by EG = 4.
Since, the point E has a coordinate of 1, it follows the point G is 4 units less or greater than 1 on the number line.
Ultimately, the possible coordinates of point G are; 1 - 4 = -3 and 1+4 = 5.

The value of the quantity after 99 months is 5228.58.
Given that, an initial value = 5900, rate of decay = 0.85% and time period = 7 years.
<h3>What is the exponential decay?</h3>
The quantity decreases slowly after which the rate of change and the rate of growth decreases over a period of time rapidly. This decrease in growth is calculated by using the exponential decay formula.
The exponential decay formula formula is 
Here, the value 
= 5900×
= 5900×0.8862
= 5228.58
Therefore, the value of the quantity after 99 months is 5228.58.

Create an equation for this and solve for h, how many hours Gina can rent the surfboard for $90.
Your equation should look like:
5h + 20 = 90
Subtract 20 from both sides.
5h = 70
Divide both sides by 5.
h = 14
Gina can rent a surfboard for 14 hours if she has $90.
