Answer:
42
Step-by-step explanation:
the 2 part of the ratio refers to 14 girls , then
14 ÷ 2 = 7 ← value of 1 part of the ratio , so
4 parts = 4 × 7 = 28 ← number of boys
total members = 14 + 28 = 42
Answer:
The answer is B, your welcome
Step-by-step explanation:
since there is no other information, we have to assume that the prices for student passes and teacher passes are the same.
therefore, the pass price per person is
$737.38 / (44 + 2) = $737.38 / 46 = $16.03
and the lunch costs per student are
$393.36 / 44 = $8.94
altogether,
$16.03 + $8.94 = $24.97
was spent for each student.
I believe it’s the second table, (5, 25), (7, 49), (9, 81).
