Answer:
Step-by-step explanation:
Given that Drake wants to save $750 so that he can take a class on computer analysis for cars.
He wants to save 125 per week for 6 weeks.
.Unfortunately, Drake had to take out a little money from his savings in the 3rd week. After 4 weeks, Drake has $470.
If he wants to have 750 after 6 weeks, he has to save $ per week
Or alternately he can save same 125 dollars so that he would have 750 $ in
3 weeks.
A: Stay with saving the original amount each week but take the class a week later than originally planned.Option B: Increase the amount of money he saves each week by $15 from his original plan.
Both are right.
c. Both options A and B will allow him to meet his goal.
Given:
The two numbers are
To find:
The highest common factor (HCF) of A and B
Solution:
We have,
...(i)
All the factors of A are prime but the factors of B are not prime. So, it can be written as
...(ii)
From (i) and (ii), it is clear that 3 is the only common factor of A and B. So,
Therefore, the highest common factor (HCF) of A and B is 3.
