Answer:

49 teachers

Step-by-step explanation:

By proportion, the number of teachers needed is found as follows:

6/102 = x/825 where x is the required number of teachers.

102x = 6*825

x = (6*825)/102

=  48.5

One week, Carlos bought 3 bags of Tabitha Tidbits and 4 bags of Figaro Flakes for $43.00. The next week he bought 3 bags of Tabi
andrezito [222]

The cost of one bag of Tabitha Tidbits costs $7.00 and cost of one bag of Figaro Flakes costs $5.50

Step-by-step explanation:

Let,

Cost of one bag of Tabitha Tidbits = x

Cost of one bag of Figaro Flakes = y

According to given statement;

3x+4y=43.00   Eqn 1

3x+6y=54.00   Eqn 2

Subtracting Eqn 1 from Eqn 2

(3x+6y)-(3x+4y)=54.00-43.00\\3x+6y-3x-4y=11.00\\2y=11.00

Dividing both sides by 2

\frac{2y}{2}=\frac{11}{2}\\y=5.50

Putting y=5.50 in Eqn 1;

3x+4(5.50)=43.00\\3x+22.00=43.00\\3x=43.00-22.00\\3x=21.00

Dividing both sides by 3

\frac{3x}{3}=\frac{21.00}{3}\\x=7.00

The cost of one bag of Tabitha Tidbits costs $7.00 and cost of one bag of Figaro Flakes costs $5.50
