Hi there!
Since the formula for finding the perimeter of a rectangle is length×2 + width × 2, we can follow this rule.
2 (4x + 5) + 2 (8x - 4)
= 8x + 10 + 16x - 8
= 24x + 2
So, the perimeter is 24x + 2.
Hope this helps!
When you see % next to a number, you multiply it by .01.
10 becomes .1
10.5 becomes .105
220*.1=22, so this is the 10% off
220*.105=23.1, so this is the 10.5% service charge.
220-22+23.1=$221.10 for the ticket.
That depends on the type of cookie that was made.... so no valid answer
