Answer:
3
Step-by-step explanation:
y = mx + b, or in this case y = b + mx
Either way, m = slope and b = y-intercept
All that is needed is that it is 270
For this case, the first thing we must do is define variables.
We have then:
t: cost of the torch
b: cost of the battery
The cost of both items in £ is given by:
Therefore, we have the following equation:
Then, we know that:
The torch costs eleven times as much as the battery.
Substituting equation two in the equation we have:
Clearing the value of b we have:
Answer:
The cost of the battery is 0.43 £
I believe the dryer costs $357.50
there's an easy way to solve this
you just divide the given price($585)
by 2 and then to one half add $65
and the answer is 65+292.5=357.5
