Options:
a) 1.3h
b) 0.7h
c) 1.5h
d) 0.3h

Answer 1

The magic ring increases the power of Eiko's healing spell by 30%. The two expressions that could represent the restored health points with the ring are 1.3h and 1.5h.

Step-by-step explanation:

The expression that represents how many health points the spell restores when Eiko is wearing the magic ring is 1.3h. This is because the ring increases the power of her healing spell by 30%, which is equivalent to multiplying the original value by 1.3.

Another expression that represents the restored health points with the magic ring is 1.5h. This is because adding 30% to the original value is the same as multiplying it by 1 + 0.3, which simplifies to 1.3.
