80 students.
2 bus rentals - $960.
$10 per student for lunch.
so we do $960 / 80 = which is $12.
so each student pays $12 for a bus rental + $10 for lunch so all together for the whole field trip it's $22.
Answer:
Option B is correct.
Step-by-step explanation:
A proportional relationship is a relationship between two variables where the ratio between the two variables is always the same.
Divide b/a for each option, the option having same ratio for the complete tables have proportional relationship
a)
9/3 = 3
12/4 = 3
20/5 = 4
b)
25/20 = 5/4
30/24 = 5/4
40/32 = 5/4
c)
12/4 = 3
15/5 = 3
24/6 = 4
d)
4/3 = 4/3
9/6 = 3/2
12/16 = 3/4
So, Option B is correct.
Answer:
5 minutes
Explanation:
.5x + 2 = y
.2x + 3.8 = y
.5x + 2 = .2x + 3.8
<u>-.2x -.2x </u>
.3x + 2 = 3.8
<u> -2 -2 </u>
<u>.3x </u>= <u>1.8</u>
.3 .3
x = 5
