Mrs. Collins is buying pumpkin doughnuts for the 7th grade teachers. One pack is $2.99 for 24 doughnuts. Another pack is $5.00 for 40 doughnuts. Which is the better deal?

$5 for 40 donuts is the better deal

Step-by-step explanation:

24 / 2.99 = 8.03 $ / donut

40 / 5 = $8/ donut

8 < 8.03 so it is the better deal

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
