Answer:
The price of the kilogram of cookies is $ 1.8
Step-by-step explanation:
Call x the price of the kilogram of candy and call y the price of kilogram of cookies
Then we know that
[tex]0.600x + 1.5y = 4.62[/tex]
We also know that the price of kilogram of cookies is 1.40 dollars cheaper than the kilogram of candy
So
[tex]y = x-1.40[/tex]
We solve this equation for x and then we substitute it in the first equation.
[tex]x = y + 1.40[/tex]
[tex]0.60 (y +1.40) + 1.5y = 4.62\\\\0.60y + 1.5y = 4.62 - 0.84\\\\2.1y = 3.78[/tex]
[tex]y = \$1.8[/tex]
