Answer:
x = 
Step-by-step explanation:
Given
3x - 
= - 
Multiply through by 10, the lcm of 5 and 2 to clear the fractions
30x - 8 = - 5 ( add 8 to both sides )
30x = 3 ( divide both sides by 30 )
x = 
=
1 notebook costs $3.45
let's turn this into 2 equations, n being notebook price, and b being binder price ->
mandy -> 3n + b = 5.85
jordan -> 2n + b = 4.65
we need to take one equation, simplify for b, and plug it into the other equation, let's take jordan's equation for this ->
b = 4.65 - 2n
plug it into mandy's equation
3n + (4.65 - 2n) = 5.85
simpify until you get n = 1.20
take this and plug it back into jordan's equation ->
2(1.20) + b = 4.65
simplify until you get b = 2.25
plus this value into mnady's equation ->
3n + (2.25) = 5.85
simplify until you get that n = 2.25
Answer:
The total cost for john's meal would be $66.84
Step-by-step explanation:
6.5% of 52.30 = 3.3995
52.30 plus 3.3995 = 55.6995
20% of 55.6995 = 11.14$
55.6995 + 11.14 = $66.84
Yes they are equivalent because they both equal 24 because 240÷10=24 and 288÷12=24 so yes they are equivalent
