Hey there!
So the original profit is y=22x; x=number of necklaces and y=profit
New:
y=29x; x=number of necklaces and y=profit
Xavier will earn $7 more if he switches to his new plan because a keyword in the question is "How many more" and that usually means to subtract, so take away 22 from 29 and you get 7
Hope this helps!

Answer: 8%
Step-by-step explanation:
Original Perimeter of the rectangle is:
= 2 * ( Length * Width)
= 2 * (20 + 30)
= 100 cm
The length increased by 10%. It therefore increased to:
= 30 * ( 1 + 10%)
= 30 * 1.1
= 33 cm
The width increased by 5%. It increased to:
= 20 * ( 1 + 5%)
= 21 cm
New Perimeter is therefore:
= 2 * ( 33 + 21)
= 108 cm
Percentage increase in perimeter is:
= (New perimeter - old) / old perimeter
= (108 - 100) / 100
= 8%
