A fundraising organization will donate $250 plus half of the money it raises from a charity event. What is the independent Variable?

What is the dependent Variable?

What is the domain?

What is the range?

Independent Variable, Domain = Charity amount

Dependent Variable, Range = Donation amount

Step-by-step explanation:

Independent Variable is the causal variable. Dependent variable is the resultant or effected variable.

In this case, organisation donates money, a constant value (250) & a proportion (half) of charity. So, independent variable (causal) is charity, effecting the dependent variable ie donation.

Equation : Let donation = d, charity = c. Given : d = f (c) , where d = 250 + c/2

Domain is set of of all values for which a function is defined, range is the set of all values that f takes. So, domain is independent variable - charity & range is dependent variable - donation.

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
