Question

Ramiro brought home ten pounds of rice to add to the 24 ounces of rice he had in the pantry. Let x represent the amount of rice Ramiro uses over the next few days. Write an algebraic expression to describe the amount of rice remaining in Ramiro's pantry

Answer 1

16 ounces in a pound.
24 oz= 1.5 ibs.
Added to 10 ibs.
Now has 11.5 ibs.

R(x)= 11.5 - x

Answer 2

The equation is :
`11.5-x`

Explanation:

Ramiro brought home ten pounds of rice to add to the 24 ounces of rice he had in the pantry.

First we will convert the ounces to pounds to get total rice in pounds.

1 ounce = 0.0625 pounds

So, 24 ounces =
`24*0.0625=1.5` pounds

Total rice in pounds =
`10+1.5=11.5` pounds.

Let x represent the amount of rice Ramiro uses over the next few days.

Therefore, the expression to describe the amount of rice remaining in Ramiro's pantry is =
`11.5-x`

Amount of rice as a function of amount used, x, in pounds:

`r(x)= 11.5- x`

Constraints can be defined as:

`0 \leq x \leq 11.5`
