Answer: B
Explanation: “Giants won 39 more games than the Cardinals”
so Cardinals+39= Giants wins (101)
The number of books sold is 473.
<u>Step-by-step explanation:</u>
- The original cost of each book = $0.64
- The selling price of each book = $0.75
The difference between the original price and selling price of the book gives the profit per book.
The profit of one book = Selling price - Original price
Let,
- The total number of books be 'x'.
- The number of books sold be 'y'.
- The unsold books is 100.
- The total profit is -12 because it was gone to a loss of $12.
Therefore, the equation is formed as
total Profit = 0.75y - 0.64x
⇒ 0.75y - 0.64x = -12 --------(1)
Total books = sold books + unsold books
x = y + 100
⇒ x-y = 100 -------(2)
Substitute x= 100+y in the eq(1),
0.75y - 0.64(100+y) = -12
0.75y - 64 -0.64y = -12
0.11y = -12 +64
y = 52 / 0.11
y = 472.7
y ≅ 473
The number of book sold is 473 books.
The total number of books is (100+473) = 573 books.
Given :
At a restaurant, Brianna and Naomi each order an appetizer for $6.50 and an entree for $9.75.
The sales tax is $0.98 and they leave a tip of $5.85.
To Find :
How much did Brianna and Naomi spend in all.
Solution :
Total expenses, T = Food + tax + tip
T = $( 6.50+9.75) + $0.98 + $5.85
T = $( 16.25 + 0.98 + 5.85 )
T = $23.08
Therefore, total expenses is $23.08 .
Hence, this is the required solution.
subtract r from c to get 8x+10
replace x with 3
8(3) +10 = 34 which in hundreds is 3400 dollars
the answer is C
Answer:
angle 1: 72.5°
angle 2: 107.5°
Step-by-step explanation:
x + y = 180
x - y = 35 ===> x = 35 + y
Substitution to find angle y:
x + y = 180
(35 + y) + y = 180
35 + 2y = 180
2y = 145
y = 72.5
Substitution to find angle x:
x = 35 + y
x = 35 + (72.5)
x = 107.5
