Jason can dig a constant rate of 7 holes every two hours. How many hours will it take him to dig 21 holes?

6 hours.

Step-by-step explanation:

7x3=21

If he digs 7 holes every 2 hours then multiply 3 by 2, which equals 6.

To make sure this is right you could solve backwards too:

21/7=3

6/2=3

Hope this helps. :)

step-by-step explanation:

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
