Step-by-step explanation:
The multiply choice were worth 4 points. Gretchen= 18x+19 Ezia= 15x+31 So basically you can enter any number. At first I picked 3 and then I did the math and I got 73 points for Gretchen and 76 points for Ezia. Then I pick four and then I got 91 points for them both. This is how I got the answer: 18x+19=15x+31 18(4)+19=15(4)+31 72+19=60+31 91=91

Let the amount of adult tickets sold be x Since the total of 380 tickets sold consists of the amount of adult tickets and the amount of children tickets that are 70 fewer: x + (x - 70) = 380 2x - 70 =380 2x = 450 x = 225 Therefore, the amount of adult tickets sold is 225
Answer:
Option a:
a=79
b=1.002
r=0.2%
Step-by-step explanation:
Q = 79 (1.002)^t
Q = a b^t = a (1+r)^t
Comparing with the formulas:
a=79
b=1.002
1+r=1.002
Solving for r: Subtrating 1 both sides of the equation:
1+r-1 = 1.002 - 1
r = 0.002
Writting r as percent:
r = (0.002) 100%
r = 0.2%
