The list below shows the items ethan and his friends bought for lunch. 2 sandwiches for $6.29 2 burgers for $7.79 1 bowl of soup for $4.99 4 drinks for $1.39 they paid 6% tax. they then paid a tip that was about twice the amount of the tax they paid. which is the closest estimate of the total amount ethan and his friends paid for their food, drink, tax and tip? a) $50 b) $35 c) $35 d) $60

6.29 * 2 = 12.58

7.79 * 2 = 15.58

4.99

1.39 * 4 = 5.56

12.58 + 15.58 + 4.99 + 5.56 = 38.71 <-- total without tax/tip

38.71 * .06 = 2.32 <-- tax

2.32 * 2 = 4.64 <-- tip

38.71 + 2.32 + 4.64 = 45.67 <-- total cost

The closet to the total cost would be option A) $50

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
