I think the expression for that is 13 • h • 3 because he gets $13 per hour and we don't know how many hours he worked so we would just put a variable and then he worked three times as many hours so multiply by 3. I might be wrong but hopefully it helps

Do you have choices?
Step-by-step explanation:
Im not sure off the top of my head
The answer is 6 units and 3 fourths
The equation of the car rental company in the form y = kx is; y = 18.50x
The equation y = kx is such that;
- k = constant of proportionality.
In essence; to determine the constant of proportionality, k in this case;
Since the company charges, $55.50 for 3 days; we have;
By evaluation k = $55.50/3
A constant rate of change means the variation in the dependent variable as dependent on the independent variable is constant

Most of the information's are already given in the question. It is important to understand the language of the problem for solving the problem. Once the language is understood, then solving the problem is easy.
Let us assume the number of black jelly beans = x
Number of yellow jelly beans = y
Then from the question we can get to a equation.
3x - 7 = y
We also know from the question that
x + y = 225
x + 3x -7 = 225
4x = 225 + 7
4x = 232
x = 232/4
= 58
So Cassidy has 58 black jelly beans out of the total of 225 jelly beans
