Problem 1
Jahmal has p pairs of shoes.: p
Kyle has one less than five times as many pairs of shoes as Jahmal.: 5p - 1
Total: p + 5p - 1 = 6p - 1
Answer: 6p - 1
Problem 2
The problem gives the original price as g. there is no s mentioned in the problem, so I don't see how you can express the higher price in terms of s. Of course, it could be that the original price is s, not g, so then just replace g with s in my answer.
The new price is g plus 15% of g.
g + 15% of g =
= g + 0.15g
= 1.15g
Answer: 1.15g
Problem 3
One package of markers costs m. 7 packages of markers cost 7m. Now you need to add 9% of 7m to 7m. If you consider 7m to be 100%, if you add 9% to 100%, you get 109%, so you need to express 109% of 7m. To find a percent of a number, multiply the percent by the number. To find 109% of 7m, multiply 109% by 7m.
109% * 7m = 1.09 * 7m = 7.63m
Answer: 7.63m
Problem 4
She earns $2.15 per hour and works 10 hours.
$2.15/hour * 10 hours = $21.50
From her salary, she earns $21.50 for the 10-hour shift.
Her customer receipts totaled r, and she earns 20% of r in addition to her salary. 20% of r = 0.2r. She earns $21.50 + 0.2r
Answer: $21.50 + 0.2r
The club sold 120 student tickets and 30 adult tickets.
<u>Step-by-step explanation:</u>
The cost of student ticket= $12
The cost of adult ticket= $20
The total cost of 150 tickets sold= $2040
Check for which option gives you the answer as $2040
<u>Option A)</u>
The cost of 30 students= 30*12= $360
The cost of 120 adults= 120*20= $2400
The total cost of 150 tickets= 360+2400= $2760 (exceeds 2040)
<u>Option B)</u>
The cost of 120 students= 120*12= $1440
The cost of 30 adults= 30*20= $600
The total cost of 150 tickets= 1440+600= $2040 <u>(correct answer)</u>
<u>Option C)</u>
The cost of 100 students= 100*12= $1200
The cost of 50 adults= 50*20= $1000
The total cost of 150 tickets= 1200+1000= $2200 (exceeds 2040)
<u>Option D)</u>
The cost of 50 students= 50*12= $600
The cost of 100 adults= 100*20= $2000
The total cost of 150 tickets= 600+2000= $2600 (exceeds 2040)
Option A: is the equation.
Explanation:
Let x represents the number of hours per month the store is open.
It is given that the the monthly rent(expense) = $1200
Also, the employee salary for each hour(expense) = $120x
Thus, the total expense C(x) is
It is also given that the income per hour(revenue) is $200x
Thus, the revenue function R(x) is
The break - even point is given by
Total expense = Revenue
Thus, is the equation.
Hence, Option A is the correct answer.
Maybe it can be 3+8=11÷2=1 remainder 1 and the population encresed once
-- Find how much 'y' changes from the first point to the second one.
-- Find how much 'x' changes from the first point to the second one.
-- The slope of the line going from the first point to the second one is
(change in 'y') / (change in 'x') .
