Answer:
2
Step-by-step explanation:
Reagan brought 2 caramel brownies.
Solve using a proportion.
[tex]\frac{?}{20}[/tex]=[tex]\frac{10}{100}[/tex]
You're trying to find how many brownies he brought were caramel. We know Reagan brought a total of 20 brownies. Therefore since you don't know how many caramel brownies he brought, the fraction would be ?/20. Next, you know he brought brownies in which 10% were caramel. In proportions, the denominator would be 100% since that is the total percentage. Therefore, the proportion would be 10%/100%. Now we just have to cross multiply.
Proportion:
[tex]\frac{?}{20}[/tex]=[tex]\frac{10}{100}[/tex]
10 x 20 = 200
200/100= 2
Thus, Reagan brought 2 caramel brownies.
