Estimate the product of 68 and 42

Answers

We can round 68 to 70
And round 42 to 40

70 x 40 = 2800

68(42)= 2856
The number 68 is multiplied by 42 and is equal to 2856

50 points! A $60 sweater is marked "8 % off." If there is a sales tax of 7%, will the actual amount paid for the sweater be greater, less than, or equal to $60? Explain your answer and show all work.

Answers

60*0.08 Multiply the price of the sweater by 0.08, or 8%
4.8 solution
60-4.8 Subtract discount from original price
55.2 solution
7/100=a/55.2 construct formula to find sales tax
a=3.864 solution
55.2+3.864 add solution to discounted price
59.064 solution
$59.06 round down to 59.06

It will be less than 60 dollars because, according to the work shown, 59.06<60.

60 x 8% = 4.8 4.8 discount
60 - 4.8 = $55.2 pricewith discount
55.2 x 7% = 3.86 tax
55.2 + 3.86 = $59.06 so it would be less than $60.00.

What is 8 divided by 1,898

Answers

well first take 8 and take the fist 2 numbers witch are 18 and see how many times 8 goes into 18. But 8 does not go into 18 so take the nearest multipul without going over wich is 16. Then figure out what times 8 is 16. 8x2=16 so write on the top 02 and put 18-16 witch is 2 then bring down the 9 witch will be 29 and find out 8x what is 29. but 8 does not go into 29 so find the nearest multipul witch is 24 and find out 8x what is 24. 8x3 is 24 so add a three at the top and put 29-24 witch is 5 and bring down the 8. So how many times does 8 go into 58. 8 cannot go into 58 so find the nearest multipul witch would be 56 and 8x what is 56. 8x7=56 so add a seven at the top and subtract 58-56 witch is 2 so your awnser would be 237 remainder 2.
