Answer:
300 burgers
Step-by-step explanation:
You can set up an equation like this: 50+0.05x=20+0.15x
Then, subtract 0.05x from both sides: 50=20+0.10x
Subtract 20 from both sides: 30=0.10x
Divide by .10 on both sides: 300=x
X represents how many burgers must be sold for the boys to have earned the same amount of money, and that is 300 burgers.
Answer:
y=-1/3x-7/3
Step-by-step explanation:
y-y1=m(x-x1)
m=-1/3
y-(-2)=-1/3(x-(-1))
y+2=-1/3(x+1)
y=-1/3(x+1)-2
y=-1/3x-1/3-2
y=-1/3x-1/3-6/3
y=-1/3x-7/3
