What is a word problem?
A word problem consists of verbal sentences describing a scenario of a problem that will be resolved mathematically.
The amount of popcorn and drink Riley bought = $51
The price of each bag of popcorn = $5
The price of each drink = $6
The number of drinks Riley bought = 2 × The number of popcorn she bought
Let D represent the number of drinks Riley bought and let P represent the number of popcorn she bought, we get;
- 6·D + 5·P = 51
- D = 2·P
Therefore;
6 × 2·P + 5·P = 17·P = 51
P = 51/17 = 3
- The number of bags of popcorn Riley bought, P = 3 Bags of popcorn
D = 2 × P
Therefore;
D = 2 × 3 = 6
- The number of drinks she bought = 6 Drinks
