Given:
The ratio of the cost of a shirt to the cost of a jacket is 2:5.
The jacket cost $240 more than the shirt.
To find:
The cost of the shirt and the cost of the jacket.
Solution:
Let x be the cost of the shirt.
The jacket cost $240 more than the shirt. So, the cost of Jacket is (x+240).
The ratio of the cost of a shirt to the cost of a jacket is 2:5. So,
Subtract 2x from both sides.
Divide both sides by 3.
So, the cost of shirt is $160.
Now, the cost of jacket is:
Therefore, the cost of shirt is $160 and the cost of jacket is $400.
