Question

For every 3 lemons you buy at a farm stand, the total cost increases by $1.80.

The constant of proportionality is
An equation that relates the total cost y and the number of lemons x is y=____x
Use the equation you wrote to complete the table.

Answer 1

he constant of proportionality is $1.80, since for every 3 lemons the total cost increases by $1.80.

The equation that relates the total cost, y, and the number of lemons, x, is:

y = 1.80 * (x/3) + b

where b is the y-intercept, which represents the cost of 0 lemons. We'll need additional information to determine the value of b.

Here is a table with the values of y and x, assuming b = 0:

x (Number of Lemons) y (Total Cost)

0 0

3 1.80

6 3.60

9 5.40
