Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. How many cups, x,
siniylev [52]

Answer:

18 cups.

Step-by-step explanation:

We are given that Bernie spends $6.50 on ingredients and cups for his lemonade stand. He charges $1.50 for each cup of lemonade. Inequality that represents this situation: 20\leq 1.50x-6.50.

To find number of cups x to make a profit of at least  $20 we will use our given inequality.

20\leq 1.50x-6.50

20+6.50\leq 1.50x

26.50\leq 1.50x

x\geq \frac{26.50}{1.50}

x\geq \frac{53}{3}

x\geq 17.6666666

Therefore, in order to make a profit of at least $20 Bernie need to sell 18 cups of lemonade.

A t shirt maker wants to open his first store.If he chooses the store on Main Street he will pay 650 in rent and will charge 32$
ch4aika [34]

Answer: 35 t shirts

Step-by-step explanation:

Let number of t shirts be x

Let profit made be y

On main street, the store costs $650,

Selling the t shirt at $32 per 1

He would make a revenue of 32x

Profit = revenue - cost accrued

y1 = 32x - 650

On Broad street, the store costs $440,

Selling the t shirt at $26 per 1

He would make a revenue of 26x

Profit = revenue - cost accrued

y2 = 26x - 440

To make same profit on either location

y1 = y2

32x - 650 =26x - 440

32x -26x = -440+650

6x = 210

x = 210/6

= 35 t shirts
