Answer:
65.62
Step-by-step explanation:
Given:
After eating a meal at a restaurant, we decided to tip 25%, building a grand total of $87.50.
To find:
Price before tip
Solution:
87.50 × 25% = 21.875
~Round~: 21.875 to 21.88
87.50 - 21 .88 = 65.62
Thus the price before the tip is 65.62
Check Answer:
<em>Formula: Higher number - Lower number ÷ original number × 100</em>
<em>Solve: </em>
<em>87.50 - 65.62 = 21.88</em>
<em>21.88 ÷ 87.50=0.25005714285</em>
<em>0.25005714285 × 100 = 25.0057142857</em>
<em>Round - 25%</em>

You can use factors to solve. Determine all the factor pairs of 24, find the two that are two numbers apart.
1, 24 X
2, 12 X
3, 8 X
4, 6 YES!
Algebraic way to solve using Quadratics:
l = 2 + w
A = lw
A = (2 + w)w Substitute (2 + w) for l
24 = (2 + w)w Substitute 24 in for the area
24 = 2w + w^2 Distribute
w^2 + 2w - 24 = 0 Set equal to 0 (put in standard form)
(w + 6) (w - 4) = 0 Factor
w + 6 = 0 and w - 4 = 0 Set each factor equal to 0.
So w= -6 or w = 4 ... -6 makes no sense for a length! So the width must be 4 and the length will be 4 + 2, which is 6.

Step-by-step explanation:
Given
A container has 19.5 liters of water
A cup can hold 210 ml of water
1 L is equivalent to 1000 ml
So, 19.5 L is equivalent to 
So, the number of requires to hold this much water

92.85 implies 92 full cups and 1 cup which is partially filled. Hence, almost 92 cups can be filled completely.
Step-by-step explanation:
Let x be the miles Kenyon ran on tuesday
Let y be the miles Kenyon ran on thursday
Given,
Mon + Tues + Wed + Thu = 8mi

also given,

Now we have x + y = 5.2 as equation 1 and -x + y = 0.4 as equation 2
Using equation 1,

Substitute this equation into equation 2.

Substitute y = 2.8 into equation 1.

Therefore Kenyon ran 2.4 miles on tuesday, and ran 2.8 miles on thursday.
