Respuesta :

In order to determine the equation, name c as the number of cans of paint and b as the number of paint brushes.

If the cost of one can of paint is $10, then, c cans costs 10c. If the cost of one paint brush is $2, b paint brushes costs 2b. Due to Sam plans to spend $50, the sum of 10c and 2b must be equal to 50.

THen, you have the following equation forthe given situation:

10c + 2b = 50
