Answer:
I think the anser maybe 17 don't trust me bc im not quit sure
[7×(-3)] × (-2)²
= (-21) × 4
= -84
x is the temperature and y is the number of swimmers. If there are 80 swimmers, then y = 80 instead of x = 80
This is how Corey should have solved
y = 1.505*x - 88.21
80 = 1.505*x - 88.21 <--- replace y with 80
1.505*x - 88.21 = 80
1.505*x = 80 + 88.21 <--- add 88.21 to both sides
1.505*x = 168.21
x = 168.21/1.505 <--- divide both sides by 1.505
x = 111.767
x = 111.8
If there are 80 swimmers at the pool, then the possible outside temperature is roughly 111.8 degrees F. This temperature seems awfully large, so it's possible that Corey's regression equation has limited scope; in other words, it isn't too useful if x is outside a given interval

Answer:
Solution given:
let the two bags of pickle & chips and be x and y.
according to the question
x+2y=$3.25
again
<u>3x+4y=$7.25 is a second equation.</u>
