Answer: $10
Step-by-step explanation:
Given
Robin and his four friends bought tickets for 
each
If each one of them bought a calculator then the total spendings are 
Suppose the cost of each calculator is 
Cost per person is given by 
For the group, it is 
Equate this to total spendings
thus, the cost of each calculator is 
1/3 +2/3 = 1 whole, so this iis the same as a^1. Answer, a^1/3 x a^2/3 = a

Answer:
(2,1)
Step-by-step explanation:
3x+y = 7
-2x +y = -3
Solve the second equation for y by adding 2x to each side
-2x+2x +y = -3+2x
y = -3 +2x
Substitute into the first equation
3x+ (-3+2x) = 7
Combine like terms
5x -3 = 7
Add 3 to each side
5x-3+3 = 7+3
5x = 10
Divide by 5
5x/5 = 10/5
x=2
Now we need to solve for y
y = -3 +2x
y = -3 +2(2)
y = -3+4
y =1
The answer is C. Infinite solutions
