Question

One says she doesn't feel well, she wants a soft drink and volunteers the remaining money to the others. How much do the other four sisters have to spend? Each sister has 10 dollars

Answer 1

$12.11

Step-by-step explanation:

From the menu:

• The cost of a Sprite = $1.55

Since she initially has $10 and volunteers the remaining money to the others:

`10-1.55=\$8.45`

Thus, the amount the other four sisters has in total will be:

`4(10)+8.45=48.45`

An inequality for the scenario will be:

`4x\le48.45`

We solve for x:

`\begin{gathered} x\le(48.45)/(4) \\ x\le\$12.11 \end{gathered}`

Each of the other four sisters has at most $12.11 to spend.
