Answer:
548, 297
Step-by-step explanation:
We can set this up as a system of equations. The first equation is for how many tickets were sold, which is x+y=845. The second equation is for the cost of the tickets, which is 3x+5.5y=3277.50. The best method for this problem (other than graphing) is elimination. First, we need to multiply one equation to get the opposite of one of the variables. The easiest one to do for this problem is x. The opposite of 3 is -3, so we have to multiply ALL of the first equation by -3. If you do this, then you get -3x-3y=-2535. Now, combine the equations:
3x + 5.5y = 3277.50
-3x -3y = -2535
________________
0x+2.5y=742.5
Now, isolate y by dividing both sides by 2.5. If you do this, you get y=297. Now, plug this in for the y in the first equation. Isolate x.
x+297=845
-297 -297

Answer:17 bags that cost 271.66$
Step-by-step explanation:
2500 / 150 = 16.6666
You cant buy 2/3 of a bag so you have to buy 17 bags.
17 x 15.98 = 271.66$
I believe its 44 but im not 100% sure

Answer:
The two numbers are 29 and 18
Step-by-step explanation:
Let x and y be the two numbers
x = 2y-7
x+y = 47
We have two equations and 2 unknowns
Substituting the first equation into the second equation
2y-7+y = 47
Combine like terms
3y -7 = 47
3y-7+7 = 47+7
3y = 54
Divide by 3
3y/3 = 54/3
y = 18
Now find x
x = 2y-7
x = 2*18 -7
x = 36-7
x = 29
The two numbers are 29 and 18
