Answer:

$-17s + 23$

Step-by-step explanation:

$- 3(s - 10) + 7( - 2s - 1)$

$- 3(s - 10) = - 3s - 3 \times ( - 10)$

$- 3s + 30 + 7( - 2s - 1)$

$- 3s + 30 - 14s - 7$

$- 17s + 30 - 7$

$\boxed{\green{= - 17s + 23}}$

The ballfield has a concession stand where they sell snow cones for $0.50 each. The ingredients to make the snow cones costs $9

Galina-37 [17]

Answer:

$4,86

Step-by-step explanation:

Profit without expenses - $0,50×20 snow cones

=$10

Let's calculate the percentage the seller takes for the ingredients daily

The seller per day makes-$0,50×35 snow cones=$17,5

This means the percent he takes for the ingredients from his/her $17,5 daily is- $9÷$17,5 ×100=51,4%.

NB-the 51,4% is the percentage of money he/she takes from the $17,5 everyday

Therefore if on the raining day he made $10

Then $10×51,4÷100=$5,14

NB-the $5,14 is the money he will take for the ingredients on the raining day

Therefore $10-$5,14=$4,86

Therefore the total profit he made with expenses is $4,86

A three-layer chocolate cake costs $24 and serves 16 . What is the cost per slice?

Fantom [35]

Hi there!

»»————-　★　————-««

I believe your answer is:

$1.50

»»————-　★　————-««

Here’s why:

Assuming that the cake has one slice per person (16 slices):

⸻⸻⸻⸻

$\frac{\text{price}}{\text{slice}}\\\\\rightarrow \frac{24}{16}\\\\\rightarrow \boxed{1.50}$

⸻⸻⸻⸻

Each slice should cost $1.50.

Hope this helps you. I apologize if it’s incorrect.
