Answer:
pls reword then i can help
Step-by-step explanation:
<span>x = number of entries
55x + 10000 - 15x ≥ 55000
First, subtract 10000 from each side
55x - 15x ≥ 45000
Now, we can combine 55x and 15x because they've both got the same variable attached
40x ≥ 45000
Now divide each side by 40 to isolate x (which is the number of entries)
x ≥ 1125
The race needs at least 1125 entries to raise at least $55,000.</span>
2*2*4+2*2*24+2*4*24
16+96+192=304
304 is the answer
Here is the square root spiral
