Answer:
He could work 10 hours as a lifeguard, and 5 hours as a tutor
Step-by-step explanation:
If he makes $16 an hour as a lifeguard
and $18 an hour as a tutor,
He could work 10 times $16, to make $160 for 10 hours.
Now we subtract this from $250, this makes $90.
We know need to find out how many times 18 goes into 90, 5 times.
So we know that he could work 10 hours as a lifeguard and 5 hours as a tutor.
I hope this is right.
I hope this helps too, have a nice day!
<span>apples = (50+x)(800-10x)
= (40000-500x+800x-10x^2)
= -10x^2 +300x + 40000
Max occurs when x = -b/(2a) = -30/(-2) = 15
= -x^2 + 30x + 4000
Max occurs when x = -b/(2a) = -30/(-2) = 15
15 trees should be added</span>
What the heckkkk. Uhmmmmm
