Graph the equation and create a equation
1 answer:
The equation for the total amount charged is y = 60 + 45x
<h3>How to create the equation?</h3>The given parameters are:
Rate = $60 per service
Installation = $45
Let y represents the total charges and x represents the number of services.
So, we have
y = Installation + Rate * x
This gives
y = 60 + 45 * x
y = 60 + 45x
See attachment for the graph of the function

notice, the gift box is just 6 rectangles stacked up to each other at the edges,
left and right, two rectangles of 32x40
top and bottom, two rectangles of 25x32
front and back, two rectangles of 25x40
so, just get the area of all 6 rectangles, add them up, and that's the "surface area" of the rectangular prism, and that's how much paper will be needed to cover it.
