Suppose Carson worked as a babysitter for '8' hours one week. What is the minimum number of full hours he would need to work at his fathers business to earn at least $96 that week?

The minimum number of full hours did Carson need to work at his father's business is 8 hours and 15 minutes  

Step-by-step explanation:

Given as :

The total number of hours did Carson spent as baby sitting on one week = 5 hours

The rate at which he earn for baby sitting = $6 per hours

The rate at which he earn as job = $8 per hours

The total amount he will earn that week = $96

Let The minimum number of full hour he need to work = h

Now, According to question

The total amount he will earn that week = total number of hours did Carson spent as baby sitting on one week ×The rate at which he earn for baby sitting  + The rate at which he earn as job × The minimum number of full hour he need to work

I.e $96 = $6 × 5 + $8 × h

Or, $96 = $30 + $8 × h

Or, 8 × h = 96 - 30

Or, 8 × h = 66

∴  h =  

i.e h = 8.25 hours

So, The number of hours = h = 8 hours and 15 minutes

Hence,The minimum number of full hours did Carson need to work at his father's business is 8 hours and 15 minutes  .

1 yd = 3 ft

48 in = 2 ft

10,560 ft = 2 mi

5 ft = 60 in

3 m = 300 cm

24 in = 2 ft

3 ft = 36 in

4 yd = 12 ft

3 mi = 15840 ft

24 ft = 8 yd

8 km = 8000 m

6 cm = 60 mm

1 yd = 36 in

2 yd = 72 in

200 cm = 2 m

5 km = 500,000 cm

7,000,000 mm = 7 km

56,000 cm = 560,000 mm
