Crafts Sold by Jessica

Jessica and Liam are selling handmade crafts at a local market. Jessica sells her crafts for $20 each, while Liam sells his for $30 each. Together, they sold a total of 150 crafts, resulting in a total revenue of $3,600. Let j represent the number of crafts sold by Jessica and l represent the number of crafts sold by Liam. You can formulate this situation with the following system of equations:

1. $$j + l = 150$$

2. $$20j + 30l = 3600$$

What is the value of j, the number of crafts sold by Jessica?
