Answer:
estimate - 400
product - 385
Step-by-step explanation:
estimate - 77 rounds up to 80
80*5=400
product - 70*5=350
7*5=35
350+35=385
To answer this, you use the formula 
where
is the simple interest that builds
is the principal (AKA the amount invested/borrowed)
is the interest rate per year
is the lenght of the loan, in years.
In your situation:
![\begin{aligned}I &= (\$3000)(5 \%/\text{year})(3 \text{ years})\\[0.5em]&= (3000)(0.05)(3)\\[0.5em]&= 450\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7DI%20%26%3D%20%28%5C%243000%29%285%20%5C%25%2F%5Ctext%7Byear%7D%29%283%20%5Ctext%7B%20years%7D%29%5C%5C%5B0.5em%5D%26%3D%20%283000%29%280.05%29%283%29%5C%5C%5B0.5em%5D%26%3D%20450%5Cend%7Baligned%7D)
This means there'd be $450 of simple interest due at the end of 3 years.
Answer:
Ok so you have to figure out what is the input, output, y-intercept (b), slope (m), and equation.
First, input is the x. Looking at the graph.
Input : 0, 10, 20
Second, output is the y. Looking at the graph.
Output : 20, 30, 40
Third, y-intercept is the b in the equation of y = mx + b. Looking at the graph.
Y-intercept (b) : 20
Fourth, slope is the m in the equation of y = mx + b. Looking at the graph.
Slope (m) : 1/2
Fifth, you have to find the equation in the form of y = mx + b. Looking at the graph.
Equation : y = 1/2x + 20
I hope this helps and if you have any other questions I would be glad to answer it, thank you :) !!
