1810.75=1800 (1 + (43/180) x)

the answer is 0.025 but I can not figure out the steps to get there.

0.025

Step-by-step explanation:

1810.75 = 1800 (1 + (43/180) x)

- divide by 1800 on both sides: 1.00597222 = 1 + (43/180) x

- subtract 1 from both sides: 0.00597222 = (43/180) x

- divide by 43/180 (0.23888889) on both sides = 0.025

0.025
