Question

The price for calculating the price to deliver a parcel of mass m kg is price ($) = 7 + 3.5m

What is the mass, in kg, of a parcel with a delivery price of $70?

Answer 1

18 Kg

Explanation:

We can use algebra to solve for the mass, m, given the delivery price, $70.

Starting with the formula:

price ($) = 7 + 3.5m

We can substitute $70 for price ($) and solve for m:

$70 = 7 + 3.5m

Subtracting 7 from both sides:

$63 = 3.5m

Dividing both sides by 3.5:

m = 18

Therefore, the mass of the parcel is 18 kg.
