The price of 600 grams of candy and 1.5 kg of cookies was 4 dollars and 62 cents. what is the price of one kg of cookies if it is 1 dollar and 40 cents cheaper than 1 kg of candy?

x = the price of 1 kg of cookies

x + 1.40 = the price of 1 kg of candy ($1 40 cents = $1.40)

The price of 600 grams of candy and 1.5 kg of cookies was 4 dollars and 62 cents = $4.62

0.60(x + 1.40) + 1.50*x = 4.62

x = $1.80

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
