Money does Chittock possess= $ 212
Amount spent per week = $9
Amount possessed by Mr. Baker = $ 51
Amount saved by Baker = $ 14
Let after x weeks they have same amount.
A.T.Q
→212 - 9 x = 51 + 14 x
taking out like terms on side
→ 212 - 51=9 x + 14 x
→ 23 x = 161
Dividing sides by 23, we get
x=7,
So, number of weeks after Mr Chittock and Mr.Baker have same amount is 7.
A set of data is given. It is required to find the first, second, and third quartile.
The given data is:
Recall that the lower quartile Q₁, or the first quartile, is the median of the lower half of the data in a set.
The lower half is:
Find the median of the lower half to get the first quartile, Q₁:
Hence, Q₁=9.
Recall that the second quartile Q₂ is the same as the median of the data.
The median is the middle element or the mean of two middle elements in a numerical data set with the elements ordered by their value.
Notice that the middle number is 15.
Hence, second quartile Q₂=15.
The upper quartile Q₃, or the third quartile, is the median of the upper half of the data in a set.
The upper half of the data is:
Calculate the median to find the third quartile, Q₃:
It follows that Q₃=17

Answer: 1.05 ft³
Step-by-step explanation:
One bag of concrete can cover 0.3 ft³.
If there are 3 ¹/₂ bags of concrete, the area that can be covered is:
= Number of bags * area per bag
= 3¹/₂ * 0.3
= 7/2 * 0.3
= 1.05 ft³
Answer:
- a) j+c=310; j-c=40
- b) (j, c) = (175, 135)
- see attached
- Jose earned $175; Camden earned $135
Step-by-step explanation:
Let j and c represent Jose's and Camden's earnings, respectively.
(a) One equation can be written for the total; another for the difference:
j + c = 310 . . . . their total earnings
j - c = 40 . . . . . the difference in their earnings
__
(b) It is convenient to add these two equations to eliminate c:
(j +c) +(j -c) = (310) +(40)
2j = 350
j = 175
Then c can be found as ...
c = j -40 = 175 -40 = 135
The solution is (j, c) = (175, 135).
__
(c) Using x for j, and y for c, we can use Desmos to graph the equations. The result is attached.
__
(d) Jose earned $175 over the summer; Camden earned $135.
