Answer:
$7.18
Step-by-step explanation:
Multiply the number of pounds bought by the cost of one pound.
(2.4 pounds)($2.99 per pound) = $7.176 ≅ $7.18
So the total number of students equals 8+17 = 25 students
Proportionally:
Thus,
boys out of the 100 students.
You could use 10, 6 and 7.
Using ten would have them all equal 50, using 6 would have them all equal 30 and using 7 would have them all equal 35.
Hope this helps!
