x=number of members

y=number of non-members

total peple was 239 so x+y=239

total collected was 593 so 2x+3y=593


we have 2 equations, 2 unknowns

x+y=239

2x+3y=593

elimination

multiply 1st equation by -2

-2x-2y=-478

add to 2nd equation


-2x-2y=-478

<u>2x+3y=593 +</u>

0x+1y=115


y=115

solve for x

x+y=239

x+115=239

x=124


124 zoo members and 115 non-members visited the zoo that day

Ugo [173]

Answer:

Step-by-step explanation:

To answer this question you first need to know what the inequality symbols mean!

≤ Less than or equal to

≥ Greater than or equal to

So if Ariel has $35 this mean the following:

$1.45 is the flat fee or y-intercept

$0.55 is the slope

This mean the following:

$1.45 + $ 0.55x ≤ $35

$0.55x ≤ $33.55

x≤61
