Question

The triangular region shows the number of possible raisins, x, and number of possible chocolate chips, y, a baker can use in a recipe.
Which combination of raisins and chocolate chips can the baker use?

A. 28 raisins and 20 chocolate chips

B. 45 raisins and 10 chocolate chips

C. 55 raisins and 12 chocolate chips

D. 33 raisins and 25 chocolate chips

Answer 1

Just failed and reviewed. The answer is A 28 and 20

Answer 2

we are going to proceed to verify each of the cases to determine the solution.

we know that

The combination of raisins and chocolate chips that can the baker use, must be in the triangular region

Let

x-------> the number of possible raisins

y-------> the number of possible chocolate chips

case A. 28 raisins and 20 chocolate chips

we have the point $A(28,20)$  

The point A lie on the triangular region

therefore

The case A is a combination of raisins and chocolate chips that can the baker use

case B. 45 raisins and 10 chocolate chips

we have the point $B(45,10)$

The point B not lie on the triangular region

therefore

The case B is not a combination of raisins and chocolate chips that can the baker use

case C. 55 raisins and 12 chocolate chips

we have the point $C(55,12)$

The point C not lie on the triangular region

therefore

The case C is not a combination of raisins and chocolate chips that can the baker use

case D. 33 raisins and 25 chocolate chips

we have the point $D(33,25)$

The point D not lie on the triangular region

therefore

The case D is not a combination of raisins and chocolate chips that can the baker use
