/50
f+
27/
50
f=
−50
/3
b+9
Step-by-step explanation:
Let's solve for <em>b</em>.
50b+3f=27
Step 1: Add -3f to both sides.
50b+3f+−3f=27+−3f
50b=−3f+27
Step 2: Divide both sides by 50.
50b
/50
=
−3f+27
/50
b=
−3
/50
f+
27
/50
Let's solve for <em>f</em>.
50b+3f=27
Step 1: Add -50b to both sides.
50b+3f+−50b=27+−50b
3f=−50b+27
Step 2: Divide both sides by 3.
3f
/3
=
−50b+27
/3
f=
−50
/3
b+9

Answer: the group rented 11 Person tubes and 4 cooler tubes
Step-by-step explanation:
There are two types of tubes, Person tube and cooler tube.
Let P represent number of Person tubes that the group rented.
Let C represent number of Cooler tubes that the group rented.
The group spends $270 to rent a total of 15 tubes and Person tube $20 Cooler tube $12.50. Two linear equations can be derived from the above information
P + C = 15 - - - - - - - 1
20P + 12.5C = 270 - - - -- - - 2
Substituting P = 15 - C into equation 2,
It becomes
20(15-C) + 12.5C = 270
300 - 20C + 12.5C = 270
- 20C + 12.5C = 270 -300
7.5C = - 30
C = 30/7.5 = 4
P = 15 - C
P = 15 - 4 = 11
32.6 cups is left because we will subtract 34 to 1 1/3
