Answer: 5 times $22.75Step-by-step explanation:1. Let n represent the number of times you can ride. To keep the cost within your budget, you must have ... 2.75n ≤ 15.00 n ≤ 5.45You can ride 5 times. You don't have enough money to ride 6 times.__2. You can choose the correct answer using estimation of the costs. (You only need to work out the numbers in detail if an estimate doesn't get you close enough.)3 all-day passes are a little more than $20 each, so cost a little more than $60.2 rides on the Mountain Coaster are another $9, so your total cost will exceed $69. That means you will get less than $31 in change from $100. The only answer choice in that range is $22.75.If you add up the costs of the passes and rides, you find they come to $77.25, so your change from $100 will be $22.75.
