Raju and Tom had the same amount of money at first. After Raju spend $2590 and Tom Spent $320, Tom had 6 times as much money as Raju.
How much did Raju have at first?
2590
Solve using model

Raju (as well as Tom) had $2724 at first.

Step-by-step explanation:

At first, each of them had x

We know that

(x - $320) = 6 * (x - $2590)

x - $320 = 6x - 6*$2590

5x = 6*$2590 - $320 = $15220

x = $3044

We can verify that

$3044 - $320 = $2724 = 6 * ($3044 - $2590) = 6 * $454 = $2724

checks out

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

definitely a. the others have almost all data points on one side of the line.
