Answer:
Sally's bonus is 2.60 more than Tom's
Step-by-step explanation:
Tom: .3(96) = 28.8
Sally: 31.4
Sally - Tom = 31.4 - 28.8 = 2.6
So first we were to told that the sum of 2 numbers add to 19
a+b=19---------(1)
and they subtract to 5
a-b=5-----------(2)
These are two simultaneous equation and can be solved by elimination:
(1) + (2):
(a+b)+(a-b)=19+5
2a=24
a=12
12+b=19
b=7
So the two numbers are 12 and 7

Let’s start with the easy part: half of the base is 3.
Therefore, 3 x h + 1 = 18
3 x h = 3h and 3 x 1 = 3
3h + 3 = 18
To solve these equations, you have to do the inverse. First you would need to minus 3:
3h = 15
3h is a simpler way of saying 3 x h, so the inverse would be a divide.
h = 5
