Emily rented the bike for five hours.
Step-by-step explanation:
perimeter of triangle = s + s + s
perimeter of given triangle = 22 + 17 + 14
= 53 cm
therefore, perimeter of given triangle is <em>53 cm</em>
mike charges 100 dollars service charge plus 65 dollars per hour.
amy charges 40 dollars service charge plus 80 dollars per hour.
the cost to repair from mike is 100 + 65 * x.
the cost to repair from amy is 40 + 80 * x.
let x = 3 and you get:
the cost to repair from mike is 100 + 65 * 3 = 295 dollars.
the cost to repaid from amy is 40 + 80 * 3 = 280 dollars.
as long as the time to repair is 3 hours or less, the cost to repair will be cheaper from amy.
