Answer:

The family paid $55.12 in sales tax. TOTAL= $148.82 + $55.12

Step-by-step explanation:

IMPORTANT FORMULA: To convert a percent to a number, you need to divide by 100.

Therefore, 8% = 8/100 = 4/50 = 2/25

The family paid a total of $689 without sales tax or tips.

8% of $689 would equal the amount that the family paid for sales tax.

We already found what 8% is equal to and keep in mind that the word "of" means multiplication.

2/25 * $689 = sales tax

$55.12 = sales tax

PART B) Now we have to find the total amount the family paid.

We have to add $689 with sales tax and tips.

We have to find tips.

Using the formula To convert a percent to a number, you need to divide by 100.

20% = 20/100 = 2/10 = 1/5

1/5 * ($689 + $55.12) = tips

tips = $148.82

TOTAL= $148.82 + $55.12

g Bob's farm harvests corns worth 83 thousand dollars (and nothing else). In each year, there is a 38% chance that a storm will

vampirchik [111]

Answer:

Hence Bob will pay a maximum of 35 thousand dollars for the insurance.

Step-by-step explanation:

The expected Utility for Bob is given by:

wealth w is measured in thousands of dollars

E(U) = Probability of storm * Utility if storm happens + (1- Probability of storm) * Utility if there is no storm)

E(U) = 0.38 * ln(20) + 0.62 * ln(83)

=0.38 * 2.9957 + 0.62 * 4.4188

=1.138378 + 2.73968

=3.878059

≅3.88

E(U) = 3.88

The wealth corresponding to this expected utility is given by w = exp(E(U)) = exp(3.88) = 48.33

≅48

= 48 dollars.

Hence the maximum Bob is willing to pay for the insurance can be given by = 83- 48

= 35 dollars.

Since it in unit of thousand dollars

Hence Bob will pay a maximum of 35 thousand dollars for the insurance.

ivanzaharov [21]

Answer:

A. Jian rounded the number of 4-ounce jars to 828 which is wrong. There are only 827 jars that can be completely filled.

B. Total number of 6-ounce jars = 551

Total money earned from 6-ounce jars = $4408

Step-by-step explanation:

A. Jian's family's collection = 3311 ounces

Number of 4-ounce jars = $\frac{3311}{4}$

= 827.75

Jian rounded it to 828 which is wrong. There are 827 jars that can be completely filled.

Cost per 4-ounce jar = $5.

Total cost = 827 × 5 = 4135

B. Now, number of 6-ounce jars = $\frac{3311}{6}$

= 551.83

≅ 551 jars

Cost per 6-ounce jar = $8

Total cost = 551 × 8 = 4408
