Final answer:
Fabrizio and his 6 friends equally share the cost of a $63 magic set. Using the equation 7 times n equals 63 and dividing by 7, we find out that each person, including Fabrizio, pays $9.
Step-by-step explanation:
To find out how much Fabrizio pays for the magic set, we need to divide the total cost by the number of friends sharing the cost, including Fabrizio. They use the equation 7 × n = 63, whetre 7 represents Fabrizio plus his 6 friends, and n is the amount each person pays. By dividing both sides of the equation by 7, we'll find out he value of n.
So, we do the calculation as follows:
- 7 × n = 63
- n = 63 ÷ 7
- n = 9
Thus, Fabrizio pays $9 for the magic set.
