Answer:
1 year 7 29/30 weeks
Step-by-step explanation:
London makes 30 a week. He needs 1799 dollars
Total cost = weekly income * weeks
1799 = 30*w
Divide by 30 on each side
1799/30 =30w/30
1799/30 = w
Lets change this to a mixed number
1799 divided by 30 is 59
59*30 = 1770 so there is 29 left over
1799/30 = 59 29/30
59 weeks 29/30 days
Hold on, there are 52 weeks in 1 year
Subtract 52 weeks and replace it with 1 year
59 weeks 29/30 weeks
+1 year - 52 weeks
------------------------------------------------------
1 year 7 29/30 weeks
The next steps depends on the definition of month. How many weeks in a month? This is a variable depending on the month
Since we know that London makes $30 a week, we can divide by the total amount that PC costs.
1,799 / 30 = 59 29/30
There are 52 weeks in one year so subtract.
59 29/30 - 52 = 7 29/30
Therefore, London saved up for 1 year and 7 29/30 weeks to have enough for the PC.
Best of Luck!
