Majed wants to earn at least $30 trimming trees. He charges $7 per hour and pays $5 in equipment fees. What are the possible numbers of hours Majed could trim trees?
Use t for the number of hours.
Write your answer as an inequality solved for t.

Answers

Answer:

Step-by-step explanation:

So basically what you want to do is set up an inequality to where 30 is on one side and the variable and the payment is on the other side. The payment is taking away from the profit, so you subtract it. It should look something like this:

30≥7t-5

Now we shall solve for t. Get all like terms to one side:

35≥7t

And divide

5≥t

At least 5 hours to make 30 dollars

When Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75. When Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120. Find the hourly rate of pay for Ben and Judy.

Answers

Answer:

They each earn 15 an hour

Step-by-step explanation:

Answer:

They both make $15

Step-by-step explanation:

In the first scenario Judy worked for 4 hours, (4)*(15)=60 plus Ben, (1)*(15)=15 which equals 75. In the second scenario, Judy works 2 hours so (2)*(15)=30 and Ben works 6, (6)*(15)= 90 which is 120.

£800 is divided between Natasha, Richard & Stephen so that Natasha gets twice as much as Richard, and Richard gets three times as much as Stephen. How much does Richard get?

Answers

Answer:

Richard gets £240

Step-by-step explanation:

Let

Stephen's share = x

Richards share = 3x

Natasha's share = 2(3x)

Total money = £800

Total money = Stephen's share + Richards share + Natasha's share

800 = x + 3x + 2(3x)

800 = 4x + 6x

800 = 10x

Divide both sides by 10

x = 800 / 10

= 80

x = £80

Stephen's share = x = £80

Richards share = 3x

= 3(80)

= £240

Natasha's share = 2(3x)

= 2(240)

= £480

Richard gets £240

Answers

Answer:

2.a. The price of 2.75 kg of pears is $4.62

2.b. The price of 0.19 kg of Pears is $ 0.3192

Step-by-step explanation:

The given parameters are;

The price of each kilogram of Pears = $1.68

Therefore, we have;

The price of a given mass of Pears = The mass in Kg of the Pears × The price per kg of Pears

2.a. The price of 2.75 kg of pears = The mass × The price per Kg = $1.68/kg × 2.75 kg = $4.62

The price of 2.75 kg of pears = $4.62

2.b. The price of 0.19 kg of Pears = The mass × The price per Kg = $1.68/kg × 0.19 kg = $ 0.3192
