A store is hoping an advertising campaign will increase their number of customers by 30%. They currently have about 80 customers
leonid [27]

Answer:

There will be 104 customers a day, after advertising campaign

Step-by-step explanation:

Current number of customers in a day in shop = 80

After advertising campaign, the customers will increase = 30%

So, new customers will be:

We can find new customers by adding new 30% customers to the current 80 customers.

First find 30% of 80

30\% \  of \ 30\\=\frac{30}{100}*80\\=24

Now, add 24 to current 80 customers.

Number of customers = 80+24 = 104

So, there will be 104 customers a day, after advertising campaign

Help me with the steps for y = 4x + 2 please.
Aleks04 [339]
You are correct. 4 is the slope and 2 is the y intercept. 

Reasoning:

y = mx + b is the slope intercept form of a line
m stands for slope
b stands for y intercept

In your case, m = 4 and b = 2.

Yesterday, Jack drove 35 1/2 miles used 1 1/4 gallons of gasoline. What is the unit rate for miles per gallon?
insens350 [35]

Answer:

28.4 miles/gallon

Step-by-step explanation:

to find the answer, you need to find the constant by dividing the miles drove by the amount of gasoline (or the other way around in terms of wording if it is not correct grammar) So you need to do 35.5/1.25 .  FYI I converted the fraction to decimal. The answer is 28.4 miles/gallon.

Hope this helped!! :)
