Answer:

1rst carriage= 125

2nd carriage = 250

3rd carriage= 275

4th carriage= 200

5th carriage = 225

6th = 250

7th = 275

8th = 300

9th = 325

then add it all = 2,025

thus, the total of the first 9 carriage is 2,025

Step-by-step explanation:

Given:

first carriage = 125

2nd " = 150

3rd. " = 170

9 carriage

solution:

125 - 150 = 25

175+ 25= 200

200+ 25= 225

225+25=250

and so on just add 25

or 25× 6= 150

150 + 175 = 325
