Explanation / Answer

1) Mark has $90 to spend on salmon at $5.00 per pound and/or chicken at $3.00 per pound. If he buys s pounds of salmon and c pounds of chicken, the equation 5s + 3c = 90 must be satisfied. How much salmon did Mark buy if he bought 15 pounds of chicken?

If mark buys c = 15 lb of chicken, thento find amt of salmon, plug c = 15

in the equation : 5s +3*15 = 90

5s = 45;

s = 9 lb ;Option C

2) The data points in th plot do not lie close to a line

Option c

3) 4(y + 2) = 5(y - 7)

4y + 8 = 5y -35

-y = -35 -8

y = 43

Option a

4)  
-20 < -4b + 4 and -4b + 4 -4

-20 < -4b+4

-4b > -24 ; b < 6

-4b +4<= -4

-4b <= -8 ; - b <= -2

b >=2

So, 2<= b < 6

Option c
