Explanation:
"Kai ordered 1,012 baseball cards"
We can write this statement as K = 1012
"Sharon ordered 5 times as many cards as Kai."
We can write this statement as S = 5K
So all we need to do is plug in K in our second equation to get:
S = 5K
S = 5*1012
Now all we do is multiply
S = 5*1012
S = 5060
So Sharon ordered 5,060 baseball cards
