This holiday season, Ms. Bastarache organized to give each 9th grader a $10 Dunkin Donuts gift card. Because she bought a lot of cards, Ms. Bastarache tipped the Dunkin Donuts employee $20. This function represents the relationship between the number of gift cards, c, and T(c), the total cost of the cards.

T(c) = 10c + 20

Be sure to answer BOTH questions below.

1. Determine the total cost, in dollars, for Ms. Bastarache to give out 93 gift cards.

2. Last year, Ms. Bastarache spent $820, how many cards did she purchase?

2. 80

Step-by-step explanation:

a is the correct

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.
