Answer:
- 6 shirts at $8
- 3 shirts at $7
Step-by-step explanation:
Let x and y represent the numbers of $8 and $7 shirts, respectively. Your system of equations can be written ...
x + y = 9
8x +7y = 69
Subtracting 7 times the first equation from the second gives ...
(8x +7y) -7(x +y) = (69) -7(9)
x = 6
Then y is ...
y = 9 -x = 9 -6 = 3

Answer: 75
solve:
For gym A
total cost= membership fee+monthly fee
membership fee=25
monthly fee=25
cost of x month=25x
total cost=25+25x
for gym B
membership fee=10
total cost=55+10x
now total cost are same
25+25x=55+10x
15x=30
x=30/15
x=2.
2 months
and amount =25+25*2=75
