Question

select the correct text.
a survey is given to children and adults about their favorite meal of the day.

the results are shown in the table.

	favorite meal
group	breakfast	lunch	dinner	total
children	30	31	24	85
adults	45	62	24	131
total	75	93	48	216

which category has an error in the table?
breakfast lunch
adults children

Explanation:

Step1: Verify Breakfast data

Given: Children who prefer breakfast = 1.5 × Adults who prefer breakfast.
Let adult breakfast count = $A$, child breakfast count = $1.5A$.
If $A=45$, then $1.5\times45=67.5$, not 30. If child count=30, adult count = $\frac{30}{1.5}=20$, not 45. The table has a mismatch here.

Step2: Verify Lunch data

Given: Adult lunch count = 2 × Child lunch count.
Adult lunch count = 62, so child lunch count should be $\frac{62}{2}=31$, which matches the table.

Step3: Verify Dinner data

Given: Children and adults both have 24 dinner respondents, which matches the table.

Step4: Verify Total counts

Children total: $30+31+24=85$ (matches). Adults total: $45+62+24=131$ (matches). Overall total: $85+131=216$ (matches).

Answer:

Breakfast
