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?

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.
