Five pounds of candy that is 20% chocolate is combined with a candy that is 40% chocolate. how many pounds of the candy that is 40% chocolate should be used to get a candy that is 25% chocolate?

5/3 pounds

Step-by-step explanation:

Five pounds of candy that is 20% chocolate is combined with a candy that is 40% chocolate

Let x be the pounds of candy that is added with 40% of chocolate

5 pounds that is 20%. 20% = 0.2

x pounds that is 40%. 40% = 0.4

mixture is x+5 pounds that is 25%. 25%= 0.25

Subtract .25x from both sides

Subtract 1 from both sides

divide both sides byu 0.15

x=5/3 pounds

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
