Which equation is equivalent to –k + 0.03 + 1.01k = –2.45 – 1.81k?

Multiply every term on both sides by 100 to remove the decimals. Then −k becomes −100k, 0.03 becomes 3, 1.01k becomes 101k, −2.45 becomes −245, and −1.81k becomes −181k. This gives −100k + 3 + 101k = −245 − 181k, which is choice A.
