Sarah wants to raise at least $50 for the American Heart Association. Her dad gives a $5 donation. She plans to raise the rest of her money by selling lemonade for $1.50 a cup.How many cups of lemonade does Sarah have to sell to raise at least $50?

Sagot :

Answer:

30 cups

Explanation:

Sarah's target = $50

If her dad gave her $5, then the amount still needed = $50-5=$45

Each cup of lemonade =$1.50

Therefore, x cups =1.50x

Since she needs to raise at least $50, then:

[tex]\begin{gathered} 1.50x\ge45 \\ x\ge\frac{45}{1.50} \\ x\ge30 \end{gathered}[/tex]

Sarah needs to sell 30 cups of lemonade to raise at least $50.
