This equation shows the linear relationship between the number of pancakes on a plate and the total weight of the plate of pancakes. x represents the number of pancakes, and y represents the total weight.

Question

Now, solve for y, the total weight when there are 4 pancakes on the plate.
y
=
1.5x + 3.5
y
=
1.5·4 + 3.5
y
=

Answer 1

To find the total weight \( y \) when there are 4 pancakes on the plate, you can substitute \( x = 4 \) into the equation \( y = 1.5x + 3.5 \):

\[ y = 1.5 \cdot 4 + 3.5 \]

Now, calculate:

\[ y = 6 + 3.5 \] \[ y = 9.5 \]

So, the total weight when there are 4 pancakes on the plate is \( y = 9.5 \) (units of weight).
