Math Question (linear equations) pleasee help!:)?
Researchers claim that vitamin C can help prevent colds, heart disease, and cancer.
Each morning Stuart adds 250 g of fruit to his yogurt as a source of vitamin C. Today, he wants to use one of the following combinations of two fruits to get 25 mg of Vitamin C:
• pear and pineapple
• banana and blueberry
• apple and cranberry
Fruit Amount of Vitamin C in 1 g of fruit (mg)
apple 0.15
banana 0.10
blueberry 0.10
cherry 0.10
cranberry 0.15
grapefruit 0.40
kiwi 0.70
mango 0.53
orange 0.49
pear 0.04
pineapple 0.25
strawberry 0.60
a) Write a system of linear equations to model each of today's possible fruit combinations.
b) Without solving or graphing, determine how many solutions each system will have. Explain how you know.
c) Solve the system that has one point of intersection.
From the table in question 1, examine at least three other fruit combinations. Solve the systems to determine if any of these combinations will provide 25 mg of vitamin C.
Thanks!:)
