A customer uses a 50% coupon good toward any household cleaning product. if the customer's purchase consists of the items below,
Vlad [161]
Here is the answer to the given problem above. Given the list of items above, since the 50% coupon only applies to any household cleaning product, this coupon will only apply to the carpet shampoo which has a price of $6.90. So 50% of this would be $3.45. So the rest of the prices of the other items would remain the same. So to sum it all, the total bill would be $8.50, without the sales tax. So we add the sales tax for this and the total would be this: $9.0525. The tax for this of 6.5% tax is 0.5525. Hope this answers your question. Have a great day!

Gwar [14]

Answer:

0.0139

Step-by-step explanation:

Given that in a test for extrasensory perception, the experimenter looks at cards containing either a star, circle, wave, or square. (The subject cannot see the cards.)

Probability for guessing a correct shape out of 4 shapes = 0.25

Each trial is independent of the other

Hence X no of correct guesses is binomial with n = number of cards = 20 and p = constant probability =0.25

the probability a subject correctly guesses at least 10 of the 20 shapes

=P(X\geq 10)\\= 1-F(9), where F represents the cumulative probability upto 9

= 0.0139

fgiga [73]

Answer:

Step-by-step explanation:

Let x represent the number of batches of soap that Lilth makes.

Let y represent the number of batches of lotion that Lilth makes.

It takes her 20 minutes(20/60 = 1/3 hours) to make a batch of soap and 35 minutes(35/60 = 7/12 hours) to make a batch of lotion. Lilth has 20 hours available to make soap and lotion. This means that

x/3 + 7y/12 = 20

4x + 7y = 240- - - - - - - - - - -1

The cost of producing each batch are $5 for the soap and $15 for the lotion. The materials to make the soap and lotion must cost at most $325. This means that

5x + 15y ≤ 325 - - - - - - - - -2

4x = 240 - 7y

x = (240 - 7y)/4

Substituting

5(240 - 7y)/4 + 15y ≤ 325

(1200 - 35y)/4 + 15y ≤ 325

1200 - 35y + 60y ≤ 1300

25y ≤ 1300 - 1200

25y ≤ 100

y ≤ 100/25

y ≤ 4

4x + 7 × 4 = 240

4x + 28 = 240

4x = 212

x = 212/4 = 53

Therefore, the solution (53, 4) means that she would make at most 53 batches of soap and at most 4 batches of lotion
