Answer:
Step-by-step explanation:
100%-17.5%= 82.5%
82.5% (divide) 82.5%= 1%
so (1% of the orginal price)=
£264 (divide) 82.5%= £320= original price
Answer:
she can buy 6 dolls
Step-by-step explanation:
In the proportional theory,
28 units is the total measurement that includes 8 units.
So, 10 + 3x - 5 is the total measurement that includes 10 units proportionally.
This means,
28 = 10 + 3x - 5
Now solve for x,
28 = 10 + 3x - 5
28 - 10 = 3x - 5
18 + 5 = 3x
23 = 3x
23 / 3 = x
So x = 23/3 or 7.6666....
Answer: Our required equation will be

Step-by-step explanation:
Since we have given that
Jack and Jill walked 4 yards every three seconds
As we know that

Now, we need to find the find the equation to represent the distance,<em>d</em>,
Jack and Jill walked over time <em>t </em>.
So here it is,

Hence, our required equation will be

X/y, y would be the 20 percent of course and x is the money earned
