A box of candy is has a value of $20. The value of the candy and the box are separate, but total $20. The candy alone is worth $19 more than the box. What is the value of just the box?

one single dollar

Step-by-step explanation:

twenty minus nineteen

the box value is $ 0.5

Step-by-step explanation:

if we don't want to get confused what we can do is 2 equations, one that represents the relationship between the box and the candy, and another that represents the money

x = candy

y = box

x = y + 19

x + y = 20

we replace in the second equation the value of x by (y + 19)

x + y = 20

(y + 19) + y = 20

y + y = 20 - 19

2y = 1

y = 1/2

y = 0.5

we replace in the first equation the value of y by its value

x = y + 19

x = 0.5 + 19

x = 19.5

so the candy value is $ 19.5 and the box value is $ 0.5
