Vincent gathered groups of 111 to 888 people and gave every group the same puzzle to solve. He recorded the number of minutes it took each group to solve the puzzle and plotted the results. Which statement is the best description of the association between these variables? a. Larger groups tended to take more time to solve the puzzle.
b. Larger groups tended to take less time to solve the puzzle.
c. There is no clear relationship between group size and the amount of time it took to solve the puzzle.

b. Larger groups tended to take less time to solve the puzzle.

Step-by-step explanation:

Given that

The group of 1 to 8 people and each group do have the same puzzle to solve

Now based on the given statements and attached graph

It can be seen that the larger number of groups would take lesser time for solving the puzzle

Therefore the option b is correct

And, the rest of the options would be wrong

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
