First, identify the digit in the hundreds place.

12,781

Left 1 - ten-thousands place

2 - thousands place

7 - hundreds place - the one we are interested in

8 - tens place

Right 1 - ones place

Now we know the 7 is in the hundreds place.

12,781

To round off to the nearest 100, all digits to the right of the digit in the hundreds place become zero.

12,781 becomes first 12,700, but now we need one more step.

Look in the original number at the digit just to the right of the hundreds digit. It is an 8. Since 8 is greater than or equal to 5, the previous digit goes up by 1, so the 7 becomes an 8, as in 12,800, and the rounded number is 12,800.

Answer: 12,800

Which of the following options is a better purchase for a bicycle? Option 1: A cash sale for $88

stellarik [79]

Answer:

Option 3

Explanation:

To get the value of the cheapest bike, best option, we will calculate the total cost of each bike:

i- Option 1:

Total cost = $88

ii- Option 2:

$5 down payment and $8 per week for 10 weeks

Total cost = 5 + 8(10) = 5 + 80 = $85

iii- Option 3:

$12 down payment and $5 per month for 12 months

Total cost = 12 + 5(12) = 12 + 60 = $72

iv- Option 4:

$20 down payment and $20 per month for 12 months

Total cost = 20 + 20(12) = 20 + 240 = $260

Now, from the above calculations, we can conclude that:

The best price would be that of option 3 ($72). It is the lowest price compared to other option.

Hope this helps :)

In 2007, the first generation of the i-phone sold for $499. The average cost of an i-phone today is $999. At a press conference

Gwar [14]

Answer: the statement made by Tim Cook is TRUE

Step-by-step explanation:

Given that;

in 2007 cost of 1st gen iphone = $499 (base year price)

cost of iphone today = $999 (current year price)

Using the Consumer Price Index

the Consumer Price Index = (cost pf product in current years/cost of product base year) × 100

we substitute

CPI = (999/499) × 100

CPI = 200.2004

so the CPI is 100.2004% higher in the current year than in the base year

Checking the inflation rate

IR = (( CPI this year- CPI last year)/CPI last year) × 100

CPI last year (base year) = 100

CPI current year is = 100.2004

IR = (( 100.2004 - 100)/100) × 100

IR = 0.002004 × 100

IR = 0.2004%

THEREFORE the statement made by Tim Cook is TRUE

(Round to the nearest tenth of a percent.) In 2011, the IRS increased the deductible mileage cost to

RUDIKE [14]

Answer:

$\%Change = 8.8\%$

Step-by-step explanation:

Given

$Initial = 51\ cents$

$Final = 55.5\ cents$

Required

Determine the percentage change

Percentage change is calculated as;

$\%Change = \frac{Final - Initial}{Initial} * 100\%$

$\%Change = \frac{55.5 - 51 }{51 } * 100\%$

$\%Change = \frac{4.5}{51} * 100\%$

$\%Change = \frac{4.5* 100\%}{51}$

$\%Change = \frac{450\%}{51}$

$\%Change = 8.8\%$

Hence, the percentage change is approximately 8.8%
