Answer:
cost = 1.35n
$33.75 for 25 songs
Step-by-step explanation:
Based on the numbers given, the cost is proportional to the number of songs downloaded. The constant of proportionality is the cost of one song: 1.35.
cost = 1.35n
For 25 songs, ...
cost = 1.35·25 = 33.75 . . . . dollars
__
The equation is ...
cost = 1.35n
0.65 x 10 = 6.5
0.65 is 10 times as much as 6.5
Georgia worked overtime on 4 of the 5 days. Her total overtime hours were
... (12-8) +(9 -8) +(10 -8) +(10 -8) = 4 +1 +2 +2 = 9
Then her pay for the week is
... (hours) × (pay per hour)
... = ((7 + 4×8) +1.5×9) × $7.50
... = 52.5 × $7.50
... = $393.75 . . . . Georgia's gross pay for the week
_____
Pay for "time and a half" can be computed by multiplying pay by 1.5 for overtime hours, or multiplying overtime hours by 1.5 and using straight pay. Either way, it is (overtime hours)×(1.5)×(straight pay).
Answer:
Stefan originally spent $110.
Stefan made a profit of $44.
Step-by-step explanation:
Given that:
Stefan sold the bike and helmet for $137 and $17
Total amount = 137+17 = $154
This is 140% of the price Stefan originally paid.
Let,
x be the original price paid by Stefan
140% of x = $154

Therefore,
Stefan originally paid $110 for the bicycle and helmet.
Profit made by Stefan = 154-110 = $44
Hence,
Stefan originally spent $110.
Stefan made a profit of $44.
