Margo must buy 60 tiles for the cost to be the same at both stores.
Step-by-step explanation:
Let x be the number of tiles purchased
Then
For Store 1:
24+0.79x
For store 2:
1.19x
For the number of tiles, we have to put both expression equal

subtracting 24 from both sides

Subtracting 1.19x from both sides

Dividing both sides by -0.4

Hence,
Margo must buy 60 tiles for the cost to be the same at both stores.

Answer:
The number of students that passed both subjects=45
Step-by-step explanation:
Step 1
Determine total number of students that passed both subjects using the expression below;
p=n-f
where;
p=number that passed both
n=total number of students
f=total number that failed both subjects
In our case;
p=unknown
n=50 students
f=5
The expression can also be written as:
number that passed both=total number of students-number that failed both subjects
replacing;
number that passed both=(50-5)=45
The number of students that passed both subjects=45
