Answer:
68
Step-by-step explanation:
First, we can try to set x as big as possible. To do that, we realize that x<=5, so the biggest value possible of x is 5.
Now, we want to set y as big as possible. To do that, we need to use the fourth equation 4x-y>=1. Since x is 5, the greatest possible value of y is 19.
After checking that x and y fit the constraints, we can plug these 2 numbers in to solve for the biggest value of c;
c=6*5+2*19=30+38=68

Pink: 2lbs = $6.40
Blue: 4-oz = $1.00
Green 1lb 8oz = $4.20
Pink = $3.20 per pound
Blue = (4 oz = 1/4 a pound) $4.00 per pound
Green = (8 oz = 1/2 a pound)(1lb 8 oz = 150% = 1 price + 1/2 of that price to equal $4.20) $2.80 per pound ($2.80 plus 1/2 of $2.80 ($1.40) = $4.20)
Karen should buy the GREEN sprinkles because it costs the least ($2.80) per pound, whereas blue costs $4.00 per pound, and pink costs $3.20 per pound.
