Jill earns a salary of $450.00 per week, plus a commission of 20% on all sales. Last week she sold $1,123 worth of goods. How much was she paid

To find 20% of the value of the goods,

1,123 x 20% (this is the same as 1,123 x 0.2)

= 224.6

Add the salary and the commission,

450.00 + 224.6

= 674.60

Therefore Jill was paid $649.60 last week
