Total gained:
chocolates%282.25%29%2Bcandies%281.75%29=87.75 ---------> working eqn
Then,
25%282.25%29%2Bca%281.75%29=P87.75
56.25%2Bca%281.75%29=87.75
ca%281.75%29=%2887.75-56.25%29=31.50
ca%2Across%281.75%29%2Fcross%281.75%29=cross%2831.50%2918%2Fcross%281.75%29
highlight%28ca=18%29 -----> total candies
Check, go back working eqn:
25%282.25%29%2B18%281.75%29=P87.75
56.25%2B31.50=P87.75
P87.75=P87.75
thank you,
