Hi, now we are going to find what is the original price per kilo of tomatoes.
00:06
Let i take x be the price per kilo of tomatoes and k be the number of kilos of tomatoes.
00:32
Then according to the given information, we can write x into k is equal to 540 pesos.
00:40
Now, here the given condition is if the price per kilo of tomato can be reduced by 2 pesos per kilo, then he could have bought 3 more kilos.
00:51
So we can write x minus 2 into k plus 3 is equal to 540.
00:59
Now from this equation, we can write k is equal to 540 x.
01:04
Then we have to substitute this value of k.
01:08
Here, then we get x minus 2 into 540 divided by x plus 3 is equal to 540.
01:19
So from this, we can write 540 minus 1080 divided by x plus 3x minus 6 is equal to 540.
01:31
So from this, we get 3x squared minus 1080 is equal to 6x...
