whole number or an integer.
Step-by-step explanation: hope this helps.
her comission is $5,220 from the sale of $87,000
It will cost $16.72 because one sqaure yard equals .836 of a meter and then multiply that by 20 and get 16.72
The measurements are 3 times as big.
These numbers are "a" and "b".
Sum is 64, so
a+b=64
Difference is 42 so
a-b=42
So you've got:

When a+b=64 and a=53 you've got:
53+b=64
b=11
So these numbers is 53 and 11.
