if the skating rink was $6 per person and the birthday party will cost $72, how many skaters will be at sami's party? 12 is the answer so now my question is what will be the new cost of the birthday party if each skater receives $2 spending money?

$96

Step-by-step explanation:

12 x 2 = 24 dollars in spending money

24 + 72 = cost of spending money and cost of skating (total cost)

24 + 72 = 96

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
