Please help I will mark brainliest if you explain WHY the answer is that in simple terms. A thanks and brainliest!

Hey there! :)

x = 7L/100km.

Step-by-step explanation:

Solve this problem by using the slope formula:

Use the points (100, 40) and (600, 5) and plug these into the formula:

Simplify:

Since this is describing the rate of consumption, we can simply write the slope as:

The question is asking for the rate of consumption over 100 km, therefore:

Cross multiply:

3500 = 500x

Divide both sides by 500:

3500/500 = 500x/500

x = 7L/100km.

$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
