Step-by-step explanation:
let a = price of one orchid plant
8 orchids would cost 8 x a = 8a
12 orchids would cost 12 x a = 12a
Let b = price of one lily plant
12 lilies would cost 12 x b = 12b
8 lilies would cost 8 x b = 8b
8a + 12b = 362 -- eqn 1
12a + 8b = 388 -- eqn 2
to solve, multiply equation 1 by 8 and equation 2 by 12
64a + 96b = 2896 equation 3
144a + 96b = 4656 equation 4
substract equation 4 from 3
80a = 1760
a = $22
Substitute for a in eqn 1 and solve for b
8(22) + 12b = 362
b = $15.5

Answer:
The number of people who owned computers last year was 1500.
Step-by-step explanation:
The information provided is as follows:
- The number of people who own computer in a small town is 2400.
- This is 60% more than the number who owned computer last year.
Let <em>X</em> denote the number of people who owned computer last year.
And <em>Y</em> denote the number of people who owned computer this year.
Then:
Y = X × (100% + 60%)
Thus, the number of people who owned computers last year was 1500.
