Question

Riley went to buy candies. She finds that a box of 10 strawberry candies costs 10 dollars and a box of 5 vanilla candies costs 15 dollars. Can you help Riley calculate the ratio of the cost of one strawberry to one vanilla candy?

• A. 3 : 1
• B. 1 : 3
• C. 1 : 15
• D. 10 : 1

Answer 1

The correct option is B 1 : 3

10 strawberry candies cost 10 $\$$.
$\Rightarrow$ Cost of 1 strawberry candy = $\frac{10}{10}=1\$$
Cost of 5 vanilla candies = 15 $\$$.
$\Rightarrow$ Cost of 1 vanilla candy = $\frac{15}{5}=3\$$
$\therefore$ Ratio of one strawberry candy to one vanilla candy = $\frac{1\$}{3\$}$= 1:3
