Help me on these questions!
1. The teacher's bill for €15 worth of copies and 8 English workbooks was €35. What did each workbook cost?
2. Patrick spent 30% of his money on a football and 60% of it on football boots. If Patrick had €3 left, how much money had he at the start?
(35 - 15) / 8 = €_________ each
0.1x = €3
Solve for x.
Sure! Let's solve these questions step by step.
1. The teacher's bill for €15 worth of copies and 8 English workbooks was €35. What did each workbook cost?
To find the cost of each workbook, we need to subtract the cost of the copies from the total bill and then divide the remaining amount by the number of workbooks.
Step 1: Subtract the cost of the copies from the total bill:
35€ - 15€ = 20€
Step 2: Divide the remaining amount by the number of workbooks:
20€ / 8 workbooks = 2.5€
Therefore, each workbook costs €2.50.
2. Patrick spent 30% of his money on a football and 60% of it on football boots. If Patrick had €3 left, how much money did he have at the start?
To find out how much money Patrick had at the start, we'll need to work backwards from the information given.
Step 1: Calculate the total amount that Patrick spent on the football and football boots:
30% + 60% = 90%
This means that Patrick spent 90% of his money, leaving him with 10% left.
Step 2: Calculate the amount of money Patrick had left (10%):
10% = €3
To find the value of 100%, we can set up a proportion. Let's represent "x" as the total amount of money Patrick had at the start:
10% of x = €3
Step 3: Setting up the proportion and solving for "x":
10/100 * x = €3
We can cross-multiply to solve the equation:
10x = 300
Divide both sides by 10:
x = 300 / 10
x = €30
Therefore, Patrick had €30 at the start.
