Nathan buys coffee and hot chocolate for his co-workers. Each cup of coffee costs $1.65 and each cup of hot chocolate costs $1.15. If he pays a total of $12.20 for 8 cups, how many of each does he buy? Nathan buys cups of coffee and cups of hot chocolate.

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

answer: y = -2.5x - 15

              (-6,0)
