Each pair of jeans is 18.645 or 18.65. This is because if you get to pairs for 37.29, then half of that is equal to 1 pair of jeans.
Answer:
Step-by-step explanation:
y = 25x +100
y- is the total money spent on the phone
x-is the number of months you had service
the relationship between x and y is proportional ( if x grows, y grows)
For example: after 2 months you would had payed $100 for the phone + the $25 each of the 2 months. y= 25*2 +100 = $150
The answer is c. if you plug in the numbers for x you get the correct numbers for y
Answer:
We assume, that the number 180 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 180, so we can write it down as 100%=180.
4. We know, that x% equals 483.6 of the output value, so we can write it down as x%=483.6.
5. Now we have two simple equations:
1) 100%=180
2) x%=483.6
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=180/483.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 483.6 is what percent of 180
100%/x%=180/483.6
(100/x)*x=(180/483.6)*x - we multiply both sides of the equation by x
100=0.37220843672457*x - we divide both sides of the equation by (0.37220843672457) to get x
100/0.37220843672457=x
268.66666666667=x
x=268.66666666667
now we have:
483.6 is 268.66666666667% of 180
Lets x = <span>number of buttons
</span><span>
Equation:
0.50x + 23.60 = 257
0.50x = 233.4
x = 466.8
Maximum number of buttons = 466
Answer:
</span><span>D) 466 buttons</span>
