What I can’t see anything
bearing in mind that
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
so, let's multiply both sides by the LCD of 7 to do away with the denominators

Answer:
$0.78
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 2.6 × 70/100
Discount = 2.6 x 0.7
You save = $1.82
Final Price = Original Price - Discount
Final Price = 2.6 - 1.82
Final Price = $0.78
Answer:
The original number was 36.7.
Step-by-step explanation:
Multipliers:
The multiplier for a increase of a% is 1 + a/100.
The multiplier for a decrease of b% is 1 - b/100.
In this question:
The original value is x.
Increased by 28%, so we have that 1 + (28/100) = 1.28x. Equals 47. We have to find x.
1.28x = 47
x = 47/1.28
x = 36.7
The original number was 36.7.
