Question

Vivien bought a box of apples for $10.50. She sold each apple for 60cents and made a profit of $1.50. How many apples were in the box?

Answer 1

n number of apples.
(n*0,60) - 10,50 = 1,50
solve this for n

Answer 2

got it?

Answer 3

Let the number of apples be x..

So, she sold all apples at 0.60x..
And she bought apples at 10.50..

So, profit made = 0.60x - 10.50
As profit is given : 1.5

So, 0.60x - 10.50 = 1.5
0.60x = 12
x = 12/0.60 = 1200/60 = 20..

So. there were 20 apples in the box...
