Soft and hard commodities.
Soft commodities are usually agricultural products such as wheat, coffee, cocoa, fruit, and sugar.
Hard commodities are usually mined, such as gold and oil.

We need to find the price of the fountain first then after the coupon. Luckily, it originally costs 100. So, it won’t be hard to find 35% off since 1%=1. 100-35=65
We gave 65 and we need to take 12 off of it.
65-12
53
So the final price will be $53.
7) A
8) B
These are the answers to the question when I put it into a calculator
Answer:
Let length of the pool be L.
Deep
A —————————————><———————————----———————————— H
.................(18.5m)
H ——————————————————————————-———><————————- A
..............................................................................................................(10.5)
In same time, Andy covers 18.5 and Hardy covers L - 18.5.
In same time, Andy covers L - 18.5 + 10.5 while Hardy covers 18.5 + L - 10.5
The ratio of these distances covered would be the same since the speeds of both people are constant.
18.5/(L - 18.5) = (L - 8)/(L + 8)
Plug in the options to find that L = 45 works.
You can write the two equations x = 4y - 7 and x + y = 93; substitute the value of x into the other equation
(4y - 7) + y = 93; combine like terms
5y - 7 = 93; add 7 to both sides
5y = 100; divide both sides by 5
y = 20; substitute this value into the other equation
x + 20 = 93
x = 73
So the numbers are 20 and 73
