Ok, the GCF is 3. and the product (watch your signs or terms), use a dot or x for multiplication (that is the operation product refers to) and a + for addition. the prpduct of 15x81 is 1,215
In the beginning, they have 50 and 180 cows respectively.
<h3>How to find the total number of cows?</h3>
The two farmers bought a total of 230 cows .
A year later the first farmer had 10% more cows than in the beginning.
Therefore,
let
x = number of cow he has initially.
A year later the percentage increase = 0.1x
whereas the second had 20% increase. Therefore,
let
y = number of cow he has initially.
A year later percentage increase = 0.2y
Hence,
x + y = 230
1.1x + 1.2y = 263
1.1x + 1.1y = 253
1.1x + 1.2y = 263
0.2y = 10
y = 10 / 0.2
y = 50
x = 230 - 50
x = 180
