Answer: answer C (8/17+19/17i)
Let the unknown number be x then given,
(4/5)x - (3/4)x = 4
(16x - 15x)/20 = 4
x/20 = 4
x=80
Let the number be n.
Four fifths of the number is 4n/5.
Three fourths of the number is 3n/4.
Four fifths of a number is more than three fourths of the number by 4.
4n/5 = 3n/4 + 4
20 * 4n/5 = 20 * 3n/4 + 20 * 4
16n = 15n + 80
n = 80
Let's check.
4/5 of 80 = 4/5 * 80 = 64
3/4 of 80 = 3/4 * 80 = 60
64 is indeed 4 more than 60 showing that 4/5 of 80 is 4 more than 3/4 of 80, so 80 is correct.
Answer: 80
An equation is formed when two equal expressions. The cost of serving a pancake will cost $4.25.
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that your total bill amount is $11.50. Also, you give a tip of 15% of your bill. Therefore, if the amount of the bill is assumed to be x then the total bill amount can be written as,
Total bill amount = Bill amount + 15% of the bill amount
$11.50 = x + 0.15x
11.50 = 1.15x
x = $11.50 / 1.15
x = $10
Therefore, the bill amount for the food was $10.
The cost of the fruit cup is $1.50, while the order was two servings of Pancakes and a fruit cup. Therefore, if the cost of a serving of pancake is assumed to be 'c'. Then we can write,
Cost of fruitcake + Cost of two pancakes = $10
$1.50 + 2c = $10
2c = $10 - $1.50
2c = $8.5
c = $8.5/2
c = $4.25
Hence, the cost of a serving of pancakes will cost $4.25.
