So for 4 cans of beans for $9, each can would be $2.25 so then we multiply that by 7 so it would be $15.75 for 7 cans of beans
25/20 × 100% = 125%
125% - 100% = 25%
25% profit :)
So, 100 * (49-37) / 37..You always do whats in parenthesis first; 49-37=12. Then you do multiplication and division, since multiplication comes first we do; 100*12=1200/37. Rounding to the nearest tenth would be 32%
Enlargement of 2.
if it were a reduction it'd be getting smaller..
