The amount of money Jade and chet will have to purchase the app is $11.6
<h3>How to solve equation?</h3>
- Jade = 8 + 2x
- Chet = 4x + 6
Where,
x = $2.50
Amount each earned:
Jade = 8 + 2x
= 8 + 2(2.50)
= 8 + 5
= $13
Chet = 4x + 6
= 4(2.50) + 6
= 10 + 6
= $16
Combined earnings = $13 + $16
= $29
Amount planned to save = 40% of combined earnings
= 40% × $29
= 0.4 × 29
= $11.6

Answer:
Step-by-step explanation:
At time zero the level was 7 gallons and at time 3 min, the level was 5 gallons.
<u>Take two points:</u>
<u>Find the rate of change:</u>
This is a 2 gallons per 3 minutes
<u>Tank holds 10 gallons, it was emptied by 3 gallons and it took:</u>
- 3 : (2/3) = 3* 3/2 = 4.5 minutes
Lines k and n are perpendicular
The slope of line k is -6
Fact: The product of slopes of two perpendicular lines = -1
So the slope of line n = -1 ÷ -6 = 1/6
The correct choice is 'D.'
