Which expression is equivalent to 1 fifth times open paren 150 x minus 80 y plus 50 minus 50 x minus 25 y plus 20 close paren ?

First combine like terms inside the parentheses: 150x − 50x = 100x, −80y − 25y = −105y, and 50 + 20 = 70. Multiplying each term by one fifth gives 20x − 21y + 14, which is choice A.
