A cup of coffee costs $4 and a cup of tea costs $3.50. If ray has $40 and has bought 6 cups of coffee, find the maximum of tea he can buy.

Coffee= $4

Tea= 3.50

6x4=$24

so with this in mind you must take 24 and divide it by the price of tea

24/3.50 is 6.8 so they max cups of tea he can buy is 6.

Hope this helps. :)

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
