Answer:
- $70
- y = 25 + 0.9x
- $250
Step-by-step explanation:
1. 10% of $50 is $5, so the purchases would come to $50 -5 = $45. Added to the $25 membership fee, the total cost for the year would be
$45 +25 = $70
2. The member pays $25 even if no purchases are made. Then any purchases are 100% - 10% = 90% of the marked price. So, the total is ...
y = 25 + 0.90x
3. $25 is 10% of $250, so that is the amount the member would have to purchase to break even on cost.
If you like, you can compare the cost without the membership (x) to the cost with the membership (25+.9x) and see where those costs are equal.
x = 25 +0.9x . . . . . x is the spending level at which there is no advantage
0.1x = 25 . . . . . . . . subtract 0.9x
25/0.1 = x = 250 . . . divide by 0.1
Answer:
0 I think
Step-by-step explanation:
30÷5 (the 5 parts from 2:3) is 6 so the first group gets 12 (2x6) and the second gets 18 (3x6)
1081.44 is the value of the quantity after 0.1 hours, to the nearest hundredth.
What Is percent in simple words?
- Rather than being expressed as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100.
- Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent.
- You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.
Based on the given conditions, formulate = 
Evaluate the equation/expression= 1081.4375
Round the number: 1081.44
Therefore, 1081.44 is the value of the quantity after 0.1 hours, to the nearest hundredth.
