Answer:
Given the statement: Joanna is paid $14 per hour.
Let x be the number of hours and y be the number of dollars paid to Joanna.
Now, writing the given situation as equation:
y = 14x
On compare with the general equation of line y= mx +b
The equation y= 14x is linear.
A proportional relationship states it is one in which two quantities vary directly with each other.
i.e, y = kx where k is constant.
Since, b = 0
so, the given equation is proportional relationship.
Therefore, the given statement is linear and proportional.

Answer:
Step-by-step explanation:
It takes 15 years to get 2.5 times the sum at 10% p.a.
Let the principal be 'P'.
Let the amount be '2.5P'
Rate = 10%
Amount = Principal - Interest
2.5 P = P - Interest
Interest = 1.5 P
So, we get that
