Answer:
Write the equation (3 $3) + (2 $7) = total cost of five hours. (B)
Step-by-step explanation:
600= 2x2x2x3x5x5
540=2x2x3x3x3x5
the common factors are two 2's, one 3 and one 5
2x2x3x5= 60
gcf of 540 and 600 = 60
Let "x" be the total # of students:
Equation:
(1/16)x= 405
x = 16*405 = 6480
We would simplify each bracket.
For the first bracket,
2 + 4 = 6
For the second bracket, 8 * 1000 = 8000
For the third bracket, 700/5 = 140
The expression becomes
6*8000*140 = 6720000
