S (x) = 360 + 0.025x

Step-by-step explanation:

Let Sm be Salary per month

Let x be sales per month

Let S (x) be savings per month

Sm = 1800 + 0.1x

where 0.1x is the commission on sales

S (x) = 20% of 1800 + 25% of 0.1x

20% of 1800 = 20/100 * 1800 = 360

25% of 0.1x = 25/100 * 0.1x = 0.025x

Therefore,

S (x) = 360 + 0.025x
