I believe the answer is A. But I am not completely sure.
Answer:
y=3x+4
Step-by-step explanation:
Hope this works
M=f+240
m+f=25000, using m from above in this equation gives you:
f+240+f=25000 combine like terms on left side
2f+240=25000 subtract 240 from both sides
2f=24760 divide both sides by 2
f=12380, and since m=f+240
m=12620
So there are 12620 males and 12380 females in the city.
C - 30%.
We know he spends less than he has expected, so we put it as a fraction calculate the percentage of the error.
So it would be:
87.5/ 125 = 0.7
And 1-0.7 = 0.3
When we move the chemical place two places to the left to make it a percentage, it will become 30%.
