Answer:
You need to try and find the total cost of the food and drink and subtract it from the amount of money Simon pays.
Two cups of coffee costs 2.78 so -
2.78 + 2.78 = 5.56
One piece of cake costs 2.85 so the total amount is
5.56 + 2.85 = 8.41
Now we know the total, we can subtract it from the money given.
10 - 8.41 = 1.59
<u>Simon will get 1.59 in change.</u>
Answer:
The price before tax was $110
Step-by-step explanation:
Here the price paid totals $129.25, including b (the pre-tax price) an 17.5% of b: b + 0.175b = $129.25. Combining the b terms, we get:
1.175b = $129.25. Solving for b by dividing both sides by 1.175, we get
b = $110. The price before tax was $110.

rate of change= temperature change / duration
rate of change= 2.5 degrees / 50 years = 0.05 degrees / year
