Question 4 of 32 Jacob is a construction worker who earns a yearly income given by the expression 2000x + 3000, where x is the n
ELEN [110]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the expression :

Jacob's yearly income :

2000x + 3000 ; x = number of hours worked per week.

Carlos income :

3800x - 40000

Managers prediction = 35

Jacob.: 2000(35) + 3000 = 73000

Carlos : 3800(35) - 40000 = 93000

Carlos will earn more than Jacob given the manager's prediction.

Number of hours required so they can earn the same amount :

2000x + 3000 = 3800x - 40000

3000 + 40000 = 3800x - 2000x

43000 = 1800x

x = 43000/1800

x = 23.88

x = 24 hours

Determine the cost of parking for each given amount of time. 5 minutes costs $ 1 hour costs $ 1 hour and 50 minutes costs $ 2 ho
SOVA2 [1]

<u>Answer:</u>

5 minutes costs $0.25;

1 hour costs $3;

1 hour and 50 minutes costs $5.5

2 hours costs $6;

2 hours and 1 minute costs $6.05;

3 and a half hours costs $10.5

<u>Explanation:</u>

Given the cost of parking for each hour is $3

Therefore, 1 hour = $3

By principle of unitary method;

a)1 hour (60 minutes) = $ 3

   5 minutes = \frac{3 \times 5}{60}

     = $0.25

b)1 hour (60 minutes) = $3

   1 hour 50 minutes = 60+50 minutes = 110 minutes =\frac{3 \times 110}{60}

    = $5.5

c)1 hour (60 minutes) = $3

  2 hours (120 minutes) = \frac{3 \times 120}{60}

   = $6

d) 1 hour (60 minutes) = $3

  2 hours 1 minutes = 120 + 1 = 121 minutes = \frac{3 \times 121}{60}

  = $6.05  

e) 1 hour (60 minutes) = $3

   3 and half hours = (3× 60) +30 = 210 minutes =\frac{3 \times 210}{60}

  = $10.5

Therefore, 5 minutes costs $0.25; 1 hour costs $3; 1 hour and 50 minutes costs $5.5; 2 hours costs $6; 2 hours and 1 minute costs $6.05; 3 and a half hours costs $10.5
