andrew-mc [135]
1. We know that 30% expressed as a decimal is 0.30

Since 30% of people were using the internet, 0.30*3200 is our answer.

Therefore 960 people were using the internet out of the 3200 surveyed.

It costs a baker 2x + 30 dollars to bake x muffins a day. Each muffin is sold for 5 dollars. How many muffins would the baker ne
Svetradugi [14.3K]

Answer:

X = 10

Step-by-step explanation:

The equation to use would be; 2x + 30 = 5x; because the baker is looking for enough to cover the costs, no more no less.

Then all you have to do is solve for the equation.

2x + 30 = 5x

Subtract 2x from each side

30 = 3x

Divide by 3

10 = x

The baker needs to sell 10 muffins in a day to make enough to cover the revenue.
