Question

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)

Answer 1

I believe it's supposed to be \((2b + 3r)\ \ \ (4b + r)\),

Answer 2

Step 1:
Combine like terms:
\(2b+3r\)
\( 4b+r\)
\[6b+4r\]

Answer 3

Because, \(\sf 2+4=6,\ then\ we\ add\ on\ the\ variable\ which\\ is\ \ so\ 6b\)
And for \(r\), \(\sf 3+1=4,\ so 4r\ remember\ that\ if\ there\ is\ just\ one\ r\ or\ one\ variable\ with\ no\ number\ behind\\ it,\ then\ that\ would\ be\ the\ same\ thing\ as\ 1r,\ or\)\(1(variable)\)
