Example Questions

Example Question #1 : System Of Equations And Inequalities: Ccss.Math.Content.Hsa Ced.A.3

There are 8 apples in a small fruit basket and 14 apples in a large fruit basket. If Sally buys a total of 5 fruit baskets that have a combined total of 58 apples, write an equation that represents the total number of apples that Sally has.

Possible Answers:

\displaystyle 8s+5l=58

\displaystyle 8s+14l=58

\displaystyle 2s+4l=58

\displaystyle 8s+58l=14

\displaystyle 14s+8l=58

Correct answer:

\displaystyle 8s+14l=58

Explanation:

To write the appropriate equation for this situation, start by identifying what is known.

\displaystyle \\\text{small fruit basket}=8\text{ apples} \\\text{large fruit basket}=14\text{ apples}

Now write the equation in words.

\displaystyle \# \text{ small fruit baskets}+\# \text{ large fruit baskets}=58\text{ apples}

Let

\displaystyle \\s=\text{small fruit basket} \\l=\text{large fruit basket}

therefore the equation becomes,

\displaystyle 8s+14l=58
