She should buy one that accords to her budget and her needs
Half of the people bought tickets at $1.50, $1.50 times 15 equals $22.50
The other half bought them at the regular price of $2.75, $2.75 times 15 equals $41.25
When we combine the two money totals, we end up with a grand total of $63.75
The Answer is 312 -- this is because, as we want know the total amount of cans, you add 5 + 3 which gives you 8.yoy can then times that by the members (39) to give you 312 which is the total
Plug in the first equation into the he second equation
3x-(2x+7)=-9
3x-2x-7=-9
x-7=-9
x=-2
plug in x=-2 into the first equation
y=2(-2)+7
y=-4+7
y=3
answer: (-2,3)
