Answer:
x = the flat fee = $1.5
y = fee per each letter sent = $0.7
Step-by-step explanation:
Let
x = the flat fee
y = fee per each letter sent
The equations
x + 35y = 26 (1)
x + 18y = 14.10 (2)
Subtract (2) from (1) to eliminate x
35y - 18y = 26 - 14.10
17y = 11.9
y = 11.9/17
y = 0.7
Substitute y = 0.7 into (1)
x + 35y = 26 (1)
x + 35(0.7) = 26
x + 24.5 = 26
x = 26 - 24.5
x = 1.5
x = the flat fee = $1.5
y = fee per each letter sent = $0.7
Answer:
$60.01
Step-by-step explanation:
To find tax you first multiply the original price x the tax(make sure to change it into a decimal)
56.35 x 0.065 =3.66
Then you add the original price and the result.
56.35 + 3.66 = $60.01
