Bodybuilding Supplements Exercises 33-36 are based on the following data on four bodybuilding supplements. (Figures shown correspond to a single serving.)15
Creatine (grams) | L-Glutamine (grams) | BCAAs (grams) | Cost ($) | |
Xtend (SciVation) | 0 | 2.5 | 7 | 1.00 |
Gainz (MP Hardcore) | 2 | 3 | 6 | 1.10 |
Stronbgevity (Bill Phillips) | 2.5 | 1 | 0 | 1.20 |
Muscle Physique (EAS) | 2 | 2 | 0 | 1.00 |
Your friend’s new personal trainer suggests that she supplement with no more than 20 grams of creatine but at least 20 grams of L-glutamine and 42 grams of BCAAs each week. She is thinking of combining Xtend and Strongevity to create a week's supply that meets her new trainer's specifications.
a. Can she combine the products in such a way that the number of servings of Xtend exceeds that of Strongevity by as much as possible? If so, how many servings of each should she combine? If not, explain why not.
b. Can she combine the products in such a way that the number of servings of Strongevity exceeds that of Xtend by as much as possible? If so, how many servings of each should she combine? If not, explain why not.
