Eric earnings equals $7
Step-by-step explanation:
Let amount earned by Robert = $10
Amount earned by Eric = $x
Robert earnings = 2x - 4
2x - 4 = 10
2x = 10 + 4
2x = 14
Divide both sides by 2
x = 14 / 2
= 7
x = 7
Eric earns $x which is equal to $7

Answer:
5$
Step-by-step explanation:
Lets call the childrens ticket x and the adult (x+3).
We then have the equation
200(x+3) + 100(x) = 2100
Divide all by 200
(x+3) + 1/2(x) = 10.5
Subtract 3
x + 1/2x = 7.5
Rewrite it
1.5x = 7.5
Divide by 1.5
x = 5
We found the factors and prime factorization of 70 and 77. The biggest common factor number is the GCF number. So the greatest common factor 70 and 77 is 7.
