Step-by-step explanation:
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
1,699*8 = 13,592
If they it’s by two then 27,184
(1699*2=3398 * 8 = 27184

Money made on memberships in January:
since t=325 m, m=19
so t=325*19=$6175
Money made on memberships in a year:
12*$6175=$74100
167 is the volume of the prism
Answer:
400cm^2
Step-by-step explanation:
For this question, you need to find the surface areas of both objects, then add them together.
For the cube:
56cm for the front
56cm for the back
42cm for the side
42cm for the other side
48cm for the top
48cm for the bottom
SA for the cube: 292cm^2
For the triangle, things are a little different. We do the same process that we did to find the SA of the cube, but we do not have to find the SA of the top side (because there isn't a top side) and we have to divide the total SA by 2 because it's a triangle.
For the triangle:
42cm for the front
42cm for the back
54cm for the slanted side
42cm for the other side
36cm for the bottom
SA for the triangle: (216/2)^2=108cm^2
292+108=400cm^2
the SA of the composite figure is 400cm^2
