a) $16
b) $28
c) $12
d) $20

answer is d) $20

Wash plus dry = $4

$4 times 4 times = $16

$1 for one detergent times the four packets = $4

Total is $20

the image is given below

since the options are not given so we draw it from the equation

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this

the answer is d
