3 0
To find your answer first you must convert 5% into a decimal which will be 0.05. Then you will have to multiply 0.05 by 579 which will give you 28.95. The final step is to add $28. 95 which is the sales tax to $579 which will give you $550.05.
Final cost: $550.05

olchik [2.2K]

Answer:

110 words in 5 min, 220 words in 10 min

Step-by-step explanation:

y = mx (there is no intercept because you can't type anything in 0 minutes)

66 = 3m

m = 22

y = 22x

5 minutes:

y = 22(5) = 110 words

10 minutes:

y = 22(10) = 220 words
