Answer:27 pieces were sold at the original price.
63 pieces were sold at the new price
Step-by-step explanation:
Let x represent the number of pieces of pottery that was sold at the original price.
Let y represent the number of pieces of pottery that was sold at the new price.
They sold some of their pottery at the original price of $9.50 for each piece. This means that the amount that they got from selling x pieces of pottery at the original price would be 9.5x
They later decreased the price of each piece by $2. This means that the new price was 9.5 - 2 = $7.5
This means that the amount that they got from selling x pieces of pottery at the new price would be 7.5y
If they sold all 90 pieces and took in $729, then the equations are
x + y = 90
9.5x + 7.5y = 729 - - - - - - - - - -1
Substituting x = 90 - y into equation 1, it becomes
9.5(90 - y) + 7.5y = 729
855 - 9.5y + 7.5y = 729
- 9.5y + 7.5y = 729 - 855
- 2y = - 126
y = - 126/- 2 = 63
Substituting y = 63 into x = 90 - y, it becomes
x = 90 - 63 = 27
Answer:

Answer: 145.1936meters
Step-by-step explanation:
Area saying for circles is apple pie r squared
Or A=3.14radius^2
Or A=3.14(6.8)^2
A=3.14(46.24)
A=145.1936meters
Step-by-step explanation:
I guess that means
1.05 / 2.1
or
1.05 ÷ 2.1
both mean the same thing.
so, let's look at
1.05 / 2.1
this is the same as
105/100 / 210/100 = (105×100) / (210×100) =
= (105×100) / (210×100) × (1/100 / 1/100)
as long as we multiply numerator (top) and denominator (bottom) always with the same thing, the general fraction or division is unchanged.
(105×100) / (210×100) × (1/100 / 1/100) =
= (105 × 100/100) / (210 × 100/100) = 105 / 210
so, yes, the division of 105 / 210 is the same as 1.05 / 2.1
Answer:
Option (C)
Step-by-step explanation:
Let the relation between amount of money (m) and Time (t) is represented by the equation,
m = ct + b
Where c = Investment per week
b = Ben already had the amount before investment
From the question,
c = $5 per week
b = $100
Therefore, equation will be,
m = 5t + 100
If duration of the investment 't' = 8 weeks
Amount in the account after 8 weeks,
m = 5(8) + 100
m = $140
Option (C) is the correct option.
