Question

the matrix shows the numbers of ice - cream cones sold at an ice - cream shop one day.
to the nearest percent, what percent of the vanilla cones sold were double cones?
chocolate vanilla mint strawberry
single cone 84 61 33 40
double cone 68 93 27 15
61% 93% 60% 40%

Explanation:

Step1: Calculate total vanilla cones

Total vanilla cones = Double - cone vanilla + Single - cone vanilla = \(68 + 61=129\)

Step2: Calculate total double - cone vanilla

Double - cone vanilla = \(68\)

Step3: Calculate the percentage

Percentage=\(\frac{\text{Double - cone vanilla}}{\text{Total vanilla cones}}\times100=\frac{68}{129}\times100\)

Wait, no. Wait the problem is "what percent of the vanilla cones sold were double cones".
Total vanilla cones \(=68 + 61=129\)
Number of double - cone vanilla \(=68\)
Percentage \(P=\frac{68}{68 + 61}\times100=\frac{68}{129}\times100\)

Wait, no, wait the options are \(40\%\), \(60\%\), \(93\%\), \(61\%\). Maybe mis - read the problem.
Wait the problem is "what percent of the vanilla cones sold were double cones"
Total vanilla cones \(=68+61 = 129\)
Double - cone vanilla \(=68\)
\(P=\frac{68}{68 + 61}\times100=\frac{68}{129}\times100\approx 52.7\%\) (wrong).
Wait, no! Wait maybe the problem is "what percent of the double cones were vanilla"
Total double cones \(=68 + 93+27+15=203\)
Vanilla double cones \(=68\)
\(P=\frac{68}{68 + 93+27+15}\times100=\frac{68}{203}\times100\)

No.
Wait another approach:
Total number of double cones \(=68+93 + 27+15=203\)
Total number of single cones \(=84 + 61+33+40=218\)
Total cones \(=203+218 = 421\)
Vanilla cones: double - vanilla \(=68\), single - vanilla \(=61\), total vanilla \(=68 + 61=129\)
If the problem is "what percent of the vanilla cones were double" \(\frac{68}{129}\times100\approx53\%\) (not in options)
If the problem is "what percent of the double cones were vanilla" \(\frac{68}{203}\times100\approx33.5\%\) (not in options)
Wait, no! Wait the matrix:
Chocolate: single \(84\), double \(68\)
Vanilla: single \(61\), double \(93\) (wait no, no! Wait the matrix is:

Total vanilla cones \(=61 + 93=154\)
Double - cone vanilla \(=93\)
Percentage \(P=\frac{93}{61 + 93}\times100=\frac{93}{154}\times100\)

Answer:

60%
