Option (b) is correct.

The monthly bill if we uses 50 additional minutes this month is $ 55

Step-by-step explanation:

Given: Your new cell phone plan charges $50 per month for 400 minutes of talk time. The plan charges $0.10 for each additional minute you talk.

We have to find the monthly bill if we uses 50 additional minutes this month.

Consider the given plan.

cell phone plan charges $50 per month for 400 minutes of talk time. The plan charges $0.10 for each additional minute you talk.

Let the monthly charge be y and x be the number of additional minutes.

So, the equation becomes,

y = 50 + 0.10(x)

For, The given month the additional minutes are 50.

so, y = 50 + 0.10(50) = 55

Therefore, The monthly bill if we uses 50 additional minutes this month is $ 55

47 - 90 = 43

43 - 180 = x

x = 137

$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.

= $3720
