Answer:
y=8000
Step-by-step explanation:
Distribute 0.07 in the numbers inside the parenthesis
So 0.19y + 0.07y + 490 = 2570
add both like terms:
0.26y + 490 = 2570
subtract both sides by 490:
0.26y + 490 -490 = 2570 -490
0.26y = 2080
then divide both sides by 0.26:
0.26y / 0.26 = 2080 / 0.26
y = 8000
