Answer:
m ≥ 6
Here, m is the number of weeks Peter need to save money.
Step-by-step explanation:
The cost of the camera = $50
The amount of money already saved = $23.25
The money saved in 1 week = $4.50
Now, The TOTAL money LEFT to be saved = Total camera cost - Money already saved
= $50 - $23.25 = $26.75
So, there is $26.75 yet to be saved.
Let us assume it takes m weeks to save $26.75.
So, money saved in m weeks = m x ( Money saved in 1 week)
or, $26.75. = m x ( $4.50)
or, m = $26.75 /$4.50 = 5.94
or, m = 5.94 ≈ 6 weeks
So, the money saved in at least 6 weeks = $26.75.
Hence, it would take AT LEAST 6 weeks to save up enough amount to buy the camera which costs $50.
⇒ m ≥ 6
