Complete question:
A postage company delivers parcels which are in the shape of a cuboid. The length of every side of the parcel must be a whole number of centimeters. The price in cents is determined by multiplying the weight of the parcel (to the nearest kilogram) by 30 and then adding on 20 times the length of the longest side of the parcel.
What is the largest parcel that weighs 5KG could be if the price for sending it is less than three dollars
Answer:
7cm long
Step-by-step explanation:
Given
Let
--- in cents
From the question, p is calculated as:
Required
Calculate the largest parcel when weight = 5 kg and price < $3
Convert price to cents
The formula: becomes
Collect like terms
Divide both sides by 20
<em>Since the length must be in whole numbers, then the largest parcel is 7cm long</em>
Algebraic expression
The signs
<
>
indicate if a number is less or higher than the other (they are not equal).
The signs
≤
≥
indicate if a number is less or higher or equal than the other
In this case, we are using the signs < or >. The tip of the sign points to the smaller number. Then
< means "less than"
Therefore, 30 less than t is equal to
30 < t
because 30 is smaller than t
