Answer:
Grace has 120 spoons in her collection
Explanation:
We can allow the variable E to represent the number of spoons Ethan has and G to represent the number of spoons Grace has.
Since we're told that Grace has 2.5 times as many spoons as Ethan, we know that
G = 2.5E
We plug in 48 for E and simplify to find the total amount of spoons Grace has:
G = 2.5 * 48
G = 120
Thus, Grace has 120 spoons in her collection as 120 is 2.5 times greater than 48 (the number of spoons Ethan has)
