Answer:

Part a) $22.95+0.43x \leq 25$

Part b) The maximum number of candy bars that you can purchase is 4

Part c) The change would be $\$0.33$

Step-by-step explanation:

Part a) Write an equation representing your shopping experience and use x for the number of candy bars

Let

x -----> the number of candy bars

we know that

The inequality that represent this problem is equal to

$2(3.50)+2(2.75)+10.45+0.43x \leq 25$

$22.95+0.43x \leq 25$

Part b) Solve the equation to determine how many candy bars can you purchase?

$22.95+0.43x \leq 25$

Solve for x

Subtract 22.95 both sides

$0.43x \leq 25-22.95$

$0.43x \leq 2.05$

Divide by 0.43 both sides

$x \leq 2.05/0.43$

$x \leq 4.8$

The maximum number of candy bars that you can purchase is 4

Part c) How much change would you have left?

If you purchase 4 candy bars

then

$22.95+0.43(4)=\$24.67$

therefore

$\$25-\$24.67=\$0.33$

In how many ways can six people sit in a six-passenger car?

nekit [7.7K]

Answer:

number of ways = 720

Step-by-step explanation:

The number of ways six people sit in a six-passenger car is given by the number of permutations of 6 elements in 6 different positions ( seats), then

number of ways = number of permutations of 6 elements = 6! = 6 * 5 * 4 *3 * 2 * 1 = 720

Since the first person that sits can be on any of the seats , but then the second person that sits can choose any of 5 seats (since the first person had already occupied one) , the third can choose 4 ... and so on.
