GEZLZIRGEB THIS IS EZXZZZ THE SECOND ONE
Answer:
5 kilograms of charcoal for $12.50
Step-by-step explanation:
first find price of 1kg:
- 3 kilograms of charcoal for $7.95= 7.95/3= $2.65 <em>($2.65 for each kg)</em>
<em>so when you get 5 kgs for $2.65 each, it would be total $13.25 (5*$2.65)</em>
<em> and that is more than the price of other one</em>
- 5 kilograms of charcoal for $12.50= 12.50/5= $2.5 <em>($2.5 for each kg)</em>
Go over 4 and up two on the negative side for (4-2) then just do the same for the other won but in the opposite square
Answer: Jim had $28 , Kirk had $16
Step-by-step explanation:
Let's represent the amount of money they had initially as k and j respectively.
From the first statement, Kirk has 12 dollars less than Jim. Mathematically, this could be expressed as :
K + 12 = J or K = J - 12
From the second sentence, we can deduce the following : If Jim's initial amount is halved, Kirk would be 2 dollars richer. This could he expressed mathematically as ;
J/2 = K - 2
NOW , let's solve both equations simultaneously.
K = J - 12 ..........(i)
J/2 = K - 2 ........(ii)
Let's substitute for k in equation ii using equation I
J/2 = J - 12 - 2
J/2 = J - 14
J = 2J - 28
Rearranging yields
2J - J = 28
J = 28
Since K = J - 12, that means k = 28 - 12 = 16
Hence initially, Jim had $28 while Kirk had $16
