Let cost of the sculpture before increase was $x.
Cost increases by 30%
so new cost = x + (30% of x) = x+0.30x = 1.30x
Given that cost after increase is $520 so both will be equal and we get:
1.30x=520
x=520/1.30
x=400
So the final answer is $400.
Dividing by a fraction is the same as multiplying by its reciprocal
example
the reciprocal of 3/4 is 4/3
hence for your problem
Distribute the 2 into the 2x and -y
Then add “like terms” which are 3x and 4x... 3y and -2y
Which then becomes 7x+y
There are no more “like terms” so that is your final answer

Answer:
B. $15.00 per person
Step-by-step explanation:
Rate of change = change in total cost ÷ change in no of friends
Thus, we can use any two given pairs on the table.
Let's use, (2, $30.00) and (3, $45.00)
Rate of change =
Rate of change =
Rate of change =
Therefore, the rate of change is $15.00 per person.
B. is the correct answer.
