A bus company operates services to and from the East, North,South and West regions of the country. A recent report from the Oper

faust18 [17]

To find the number going to and from West is 165,000.

The number of bus passes from Southern services is 29,000.

<h3>The two-way tabulation</h3>

East------------------- 80,000

North------------------- 124,000

South------------------- 61,000

West-------------------- 165,000

Total--------------------------- 430,000

To find the number going to and from West:

80,000 + 124,000 + 61,000 + x = 430,000

265,000 + x = 430,000

x = 430,000 - 265,000

x= 165,000.

<h3>Table for the method of payment</h3>

<h3>Bus Passes </h3>

Northern services-------------------- 43,000

Western services-------------------- 51,000

Eastern services---------------------- 35, 000

Southern services---------------------- 29,000

Total----------------------------------------------158,000

Let x be the unknown variable,

43,000 + 51,000 + 35,000 + x = 158,000

129,000 + x = 158,000

x= 158,000 - 129, 000

x= 29,0000

Sage borrowed $4500 from her parents to buy a new car. So far she has repaid $2740. If sage repays her parents $110 a month, how

Naily [24]

Answer:

16 months

Step-by-step explanation:

Hey there!

This would be the correct answer because first you need to subtract the amount she paid from the amount she owes.

$4500-2740$

$=1760$

After that divide that answer from 110

This is because she will be paying 110 each month

$1760/110$

Once you calculate that you will get 16.
