Question

marcos makes a table to show how many students in his class wear glasses. there are 18 boys and 14 girls in the class. there are 5 boys and 7 girls who wear glasses. which table correctly shows the data?
first table: boys - glasses:5, no glasses:13, total:18; girls - glasses:7, no glasses:7, total:14; total - glasses:12, no glasses:20
second table: boys - glasses:5, no glasses:7, total:12; girls - glasses:9, no glasses:11, total:20; total - glasses:14, no glasses:18
third table: boys - glasses:14, no glasses:5, total:19; girls - glasses:18, no glasses:7, total:25; total - glasses:32, no glasses:12
fourth table: boys - glasses:14, no glasses:18, total:32; girls - glasses:5, no glasses:7, total:12 (partial as last row cut off)

Explanation:

Step1: Check Boys' No Glasses

Total boys: 18, boys with glasses: 5. So no glasses boys: \(18 - 5 = 13\).

Step2: Check Girls' No Glasses

Total girls: 14, girls with glasses: 7. So no glasses girls: \(14 - 7 = 7\).

Step3: Check Totals

Glasses total: \(5 + 7 = 12\). No glasses total: \(13 + 7 = 20\). Total students: \(18 + 14 = 32\) (matches first table's totals logic).

Answer:

The first table (with Boys: 5, 13, 18; Girls: 7, 7, 14; Total: 12, 20, 32)
