Need help to sort out Mathmatic question
A farmer makes a profit of x pence on each of the(x+5)eggs his hen lays.If his total profit was 84 pence,what is the number of eggs his hen lays?
ps:in this case,i am not sure what x stands for.Is it an unknown number or a real amount
答
一个老农的鸡下蛋,X+5个鸡蛋卖x便士.如果总利润是84便士,有多少个鸡蛋.
肯定是未知数了帮你做好了
X(X+5)=84
X=7
负解舍去
鸡蛋数就是X+5=12
