Answer:
Explanation:
The 
th term of an arithmetic sequence is explicitly defined as 
where 
is the first term of the sequence and 
is the the common difference.
From the given first five terms of the sequence we can see that the first term is 
so 
.
The common difference, , can be calculated by 
so we'll find the common difference of the given sequence by letting 
.
Now let's plug everything we know.
0.647 rounded to the nearest tenth = 0.6
His hourly rate is $13.75.
Let x be the hourly rate. Since he works 20 hours that week, the hourly wages are given by 20x. We add to that his commission, which is 16% of the $1500 in sales, or 0.16(1500). This totals to 515:
20x + 0.16(1500) = 515
20x + 240 = 515
Subtract 240 from both sides:
20x + 240 - 240 = 515 - 240
20x = 275
Divide both sides by 20:
20x/20 = 275/20
x = 13.75.
Answer:
t
Step-by-step explanation:
1) 32.75 times .40= 13.10
2) 32.75-13.10=19.65
The sale price is $19.65
