Answer:
<u>Given function:</u>
<u>Each element represents:</u>
- y - total cost
- 3 - rate per hour
- x - number of hours
- 2 - flat rate charge
2 and a half kg of tomatoes- 1.50 per kg.
Since we know how much it costs per kg and we know how many kg's there are (2) we would add 1.50 and 1.50 to make 3. and about half of 1,50 is 75 so I would say <span>£</span>3.75
The answer will be y^2/4 (I’ve written up properly on the photo as I can’t type it)
To get the answer you need to find out how many miles she bikes in 10minutes.
Divide 50minutes by 10 you get 5. Now you divide 10(miles) by 5 and you get 2. So it means that in 10minutes she bikes 2miles. Now you need to know how many miles she bikes in 90minutes so if she bikes 2 in 10 then because 90:10=9 you do 2*9=18. She can bike 18miles in 90minutes. :))
