One week, Gabriel bought 2 bags of beans and 3 bags of rice. The next week, he bought 4 bags of beans and 1 bag of rice. Let b represent the cost of each bag of beans and r represent the cost of each bag of rice. Simplify the expression for the total cost, shown below.

(2b + 3r) + (4b+ r)

2b + r
5b + 5r
6b + 2r
6b + 4r

Answer 1

to simplify (2b + 3r) + (4b+ r) simply combine like terms

for example, you can add the b terms, then add the r terms

2b + 4b = ?
3r + r = ?
