Word Problem Practice

You sell small loom bracelets for $2 and and large loom bracelets for $4. You want to make $40. This situation can be modeled by the equation 2x+4y=40 where x is the number of small loom bracelets you sell and y is the number of large loom bracelets you sell 1.) Find the intercepts of the graph 2.) Graph the equation 3.) What does the x and y intercept mean in this situation? 4.) If you sell 10 small bracelets, how many large bracelets are sold to make $40? x-intercept: (20,0) y-intercept: (0,10) x-intercept: when 0 large bracelets are sold y-intercept: when 0 small bracelets are sold 2(10) + 4y = y = 40 4y = 20 y = 5 large bracelets small bracelets large bracelets
