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
750ml= 0.75l
250ml=0.25l
2L+(0.75L+0.25L)+1.5L= 4.5L
One L left, to find original amount
4.5L+1L=5.5L
Answer:
$ 8.45
Step-by-step explanation:
3.85 * 3 = 11.55
20 - 11.55 = 8.45
Good evening ,
Answer:
<h2>JK = 8.4.</h2><h2>KL= 11</h2>
Step-by-step explanation:
