Remark
This is called an extraneous information question. That means you have a piece of information you don't need. You'll get a lot of these in math courses yet to come. The piece of information you don't need is 79.95.
All you need are the other two numbers.

sale price= 62.79
Pocket money = 59.20
Formula
Amount needed = Sale price - Pocket money
Solution
Amount needed = 62.79 - 59.20
Amount needed = 3.59
Answer:
y = 5/7 x - 6
Step-by-step explanation:
For two lines to be perpendicular, the product of their slope must be -1
The slope of the given function is -7/5
Let the slope of the required function be m
m * -7/5 = -1
7/5 m = 1
7 = 5m
m = 5/7
The slope of the line perpendicular to the line is 5/7
The required equation (using any value of the y-intercept) is expressed as;
y = 5/7 x - 6
Note that the y-intercept value was assumed and any value can be used
Answer:
The answer is (x - 9)(x - 2), or x2 - 11 + 18.
Step-by-step explanation:
Well, think about it. What two numbers add to -11 and multiply to get 18? -9 and -2 add to get -11 and multiply to get 18.
