Solve this Linear Algebra Question

Dr. Ng (not his real name) works part time as a fruit seller. He goes to the fruit
wholesaler every day with $200 and buys back 3 types of fruits to sell at his stall. On
a particular day, he decides to choose from oranges, grapefruits and mangoes and finds
these fruits selling at the following prices:
Orange: $0.50 per orange
Grapefruit: $1.10 per grapefruit
Mango: $1.50 per mango
(i) If Dr. Ng wants to buy exactly 100 fruits and use all his $200, write down a
linear system with two equations and three variables.
(ii) Determine if it is possible for Dr. Ng to make his purchases.
Important: For this question, it is obvious that Dr. Ng is not allowed to
buy a fraction of a fruit, neither is it possible that the number of a particular
fruit he buys is negative.

Branch of mathematics concerned with mathematical structures that are closed under operations like addition and scalar multiplication. It is the study of linear combinations, vector spaces, lines and planes, and some mappings that are used to perform linear transformations. Linear algebra also includes vectors, matrices, and linear functions. It has many applications from mathematical physics to modern algebra and coding theory.
