Answer:

a.p/100

b.56

Step-by-step explanation:

2% of p=k

2/100 ×p=k

2p/100=k

Cross multiply 2p=100k

P=100k/2

p=50k

Let's make k the subject of formula

k=p/50

So 50% of k in terms of p

50/100×k

And k=p/50

So let's substitute

50/100×p/50

P/100

Therefore 50%of k=p/100

Let the unknown number be x

10% of x is 7

10/100×x=7

10x/100=7

Cross multiply

10x=(100)(7)

10x=700

Divide both sides by 10

X=70

So 80% of 70

80/100×70

5600/100

=56

Therefore 80% of 70=56

The gas tank of the truck holds 30 gallons the gas tank of a passenger car holds 50% less how many gallons does it hold?
love history [14]

Answer:

15 gallons

Step-by-step explanation:

To find how much the passenger car holds, we need to first find what 50% of the trucks gas tank holds.

Truck Gas Tank = 30 gallons

Now we find how much 50% of 30 is:

50% = 0.50

Total = 30 x 0.50

Total = 15 Gallons

So the passenger car holds 15 gallons of gas.

Please solve the equation (15m + 3)/2 = -6
stiv31 [10]

Answer:

m = - 1

Step-by-step explanation:

Given

\frac{15m+3}{2} = - 6

Multiply both sides by 2 to clear the fraction

15m + 3 = - 12 ( subtract 3 from both sides )

15m = - 15 ( divide both sides by 15 )

m = - 1

kondaur [170]

Answer:

The total commission is $8905

Step-by-step explanation:

The commission on first $80000 = 2%

The commission on next $80000 = 4%

The commission on the sales of more than $160000 = 5%

Now we have to calculate the total commission on the amount of $242100. Let divide the amount in three parts, $80000 + $80000 + $82100 = 242100

Now total commission = $80000×2% + $80000 ×4% + $82100×5%

Total commission = $8905
