Answer:
Step-by-step explanation:
30% of a dollar...
0.30(1) = 0.30.....so 30% of a dollar is 30 cents
1 quarter and 1 nickel = 0.30
3 dimes = 0.30
2 dimes and 2 nickels = 0.30
6 nickels = 0.30
3 nickels, 1 dime, 5 pennies = 0.30
10 pennies, 2 nickels, a dime = 0.30
30 pennies = 0.30

Answer:
Step-by-step explanation:
You want to set up a system. We are given some points fo we can set up inputs and outputs. F(0) = 5, given by point (0,5). and F(3)=135, given by point (3,135). The exponential function general equation is F(x)= a(b)^x. plug in out functions into the general equation to get a(b)^0=5 and a(b)^3=135. Then you simplify and solve for a. In the equation a*b^0=5, anything to the power of 0 is 1. so a*1=5. Therefore a=5. we plug in the a to the second equation to find b. 5*b^3=135. b^3=27. b=3 from simplifying. Therefore, the equation should be 5(3)^x. THATS IT!
