Oduvanchick [21]

Answer: The equation using one variable that can be used to find the total number of pounds of milk chocolate and caramels in the candy is $0.9x+3=x$

x= Weight of candy in pounds

0.9x = Weight of milk chocolate.

Step-by-step explanation:

Given, Martin is making a candy that contains 90% milk chocolate and the rest caramels. The candy has 3 pounds of caramels.

Let x= Weight of candy in pounds

Then, 0.9x = Weight of milk chocolate.

Then, According to the question

$0.9x+3=x\\\\\Rightarrow\ x-0.9x=3\\\\\Rightarrow\ 0.1x=3\\\\\Rightarrow\ x=\dfrac{3}{0.1}=30$

So, Weight of milk chocolate. = $0.9\times30=27$

Hence, the equation using one variable that can be used to find the total number of pounds of milk chocolate and caramels in the candy is $0.9x+3=x$
