I can do A, I think.
Part A: Marina rented a coat at $285 for 3 days. If as rents the same coat for 6 days she has do pay a total rent of $510. <span>Write an equation in the standard form to represent the total rent (y) that Marina has to pay for renting the coat for x days.
</span><span>First, find out the base price. If it was $285 for 3 days, then it's: 285/3, which equals $95 per day to rent the coat. Now you can just write the equation. Use the letters x and y to represent the data they want in the equation.
y (total rent) = 95x (x being the number of days). So your equation will be y = 95x, and if someone wanted to solve it they'd just need to give the value of "x"</span>
Plugging in the data points into a quadratic regression application, we get the following regression:
y = ax^2 + bx + c,
where:
a= 0.00267857
b= 0.0110714
c= 2.85743
with an R² value of 0.9851
<h3>Given fraction:</h3>
<em>Step</em><em> </em><em>1</em>: Devide both numerator and denominator by 4 and you'll get:
▪
It would be 400,000 cause you would roimd the 4
