According to the graph above, the sale of fruits and vegetables in Store S last week accounted for what percent of the total sales income for the week?
(1) Last week the total income from the sale of fruits and vegetables in Store S was $16,000.
(2) x = 2y
Target question: The sale of fruits and vegetables in Store S last week accounted for what percent of the total sales income for the week? Statement 1: Last week the total income from the sale of fruits and vegetables in Store S was $16,000. x represents the PERCENTAGE of revenue from the sale of fruits and vegetables
The graph tells us that the total revenue was
$100,000$16,000/
$100,000 = 16/100 = 16%
The answer to the target question is
16% of sales are from fruits and vegetablesSince we can answer the
target question with certainty, statement 1 is SUFFICIENT
Statement 2: x = 2yWe know that the SUM of all of the percentages in the graph is 100%
In other words:
40% + 8% + y% + 28% + x% = 100% Simplify:
76% + y% + x% = 100% Simplify again:
y% + x% = 24% We're told that x = 2y
Divide both sides by 2 to get: 0.5x = y
Take the equation
y% + x% = 24% and replace y with 0.5x to get:
0.5% + x% = 24% Simplify:
1.5x% = 24% So x = 24/1.5 = 16
In other words,
16% of sales are from fruits and vegetablesSince we can answer the
target question with certainty, statement 2 is SUFFICIENT
Answer: D
