 
 <prompt> To make a lasagna Martha needs 1.5kg of cheese and 500 grams of meat. The cheese costs $6 per kilogram, and the meat $8 per kilogram. How much does Martha need to pay for the ingredients? <response>: ```500 grams is 0.5 kilogram, so for the meat, Martha needs to pay 0.5 * 8 = $4.
For the cheese, Martha needs to pay 1.5 * 6 = $9.
So in total for the ingredients, Martha needs to pay 4 + 9 = $13.

The answer will be 13.```
