Suppose y varies directly with x, and y=25 when x=140. What is the value of x when y=36?

Make y equal to the constant (k)multiplied by x which is. Y=KX Then put the numbers in it therefore k=0•18. Then put the new values into the y=KX 36=0•18x, X=36/0•18 therefore x=200

y=25........x=140
y=36.........x=?
x=(36*140)/25
x=5040/25
x=201,6
