Question

6b 4r represents the total cost of the rice and beans Gabriel bought. If he returns 2 bags of beans and 1 bag of rice, the expression that represents the total cost after the return is (6b 4r) – (2b r). What is this expression after simplifying?.

Answer 1

The total cost of rice and beans bought by Gabriel is 6b + 4r. The return cost of rice and beans is 2b + 1r. So the final cost of the rice and beans is  (6b + 4r) -(2b + 1r).

The simplified expression of the final cost is 4b + 1r.

What is simplification?

Simplification can be defined as a process of replacing a mathematical expression by the cancellation of common factors, regrouping of terms in the same variable to get the more simple form of the given expression.

Given that 6b + 4r represents the total cost of the rice and beans Gabriel bought.

He returns 2 bags of beans and 1 bag of rice. This can be written as,

$2b + 1r$

Then, the total number of bags of rice and beans is given as,

$(6b+4r) - (2b+1r)$

When we simplify the above equation, we get,

$6b + 4r - 2b -1r$

$6b - 2b + 4r - 1r$

$4b + 1r$

Hence we can conclude that the expression for rice and beans after the return is (4b+1r).
