Will is building shelves for his room. He has $50 to buy supplies and knows he’ll need shelving board and stain for his project. He already has his other materials from previous projects. Shelving board (s) costs $3.75 per piece, and stain (t) costs $11.99 per gallon. Write the equation that represents this relationship between the money he has and the amount of materials he may be able to buy.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition,substraction, multiplication and division

Given that:-

He has $50 to buy supplies and knows he’ll need shelving board and stain for his project. He already has his other materials from previous projects. Shelving board (s) costs $3.75 per piece, and stain (t) costs $11.99 per gallon.

Suppose the quanitty of shelving board is 's' and the stain is 't' the expression will be given as:-

3.75s + 11.99g ≤ 50

The total equation is representing the relationship between the amount of money he has and the quantity of the material he can buy under the $50.

Therefore the relationship between the quantity of shelving board and stain will be 3.75s + 11.99t ≤ 50.
