Answer:
a: f=
24y−17
/3y−1
b: x=−23
Step-by-step explanation:
8x + 4y + 6 <= 70
x = # of salads
y = # of drinks
If he buys 4 salads then
8x + 4y + 6 <= 70
8(4) + 4y + 6 <70
32 + 4y + 6 <= 70
4y + 38 <= 70
4y <= 32
y <= 8
Answer

A)
Increase %= (new # - old #)/old * 100
new= 8
old= 5
Increase %= (8-5)/5 * 100

=0.60 * 100
=60% increase
B)
Decrease %= (old # - new #)/old * 100
new= 5
old= 8
Decrease %= (8-5)/8 * 100
= 3/8 * 100
= 0.375 * 100
= 37.5% decrease
