What single decimal multiplier would you use to increase by 4% followed by a 3% increase
Mandarinka [93]

Answer:

1.0712

Step-by-step explanation:

if you increase by 4%, it means you will have a new total of 104%. In decimals it is 1.04 (divide your percentage by 100) after that you do the same with the 3% increase. you'll have a new total of 103%. In decimals 1.03. If you want to know what single multiplier you can use, you need to multiply the both decimals. So you get 1.04 x 1.03 = 1.0712

hope this will help you, have a nice day!

Sam has $3.30 in quarters and dimes, and the total number of coins is 18. How many quarters and how many dimes?
zhuklara [117]

Answer:

Quarters: 10

Dimes: 8

Step-by-step explanation:

Constraints

value: 0.25q + 0.10d = 3.30

count: q + d = 18

q = 18 - d

0.25(18-d) + 0.10d = 3.30

4.50-0.25d+0.10d = 3.30

4.50-0.15d = 3.30

-0.15d = -1.20

d = 8

q + d = 18

q + 8 = 18

q = 10

Check:

0.25(10) + 0.10(8) = 3.30

2.5+ 0.80 = 3.30

3.30 = 3.30

aleksley [76]

Answer:

"34,814" is the correct solution.

Step-by-step explanation:

The given values are:

Intercept coefficient,

\beta_0 = 23,859

Production coefficient,

\beta_1 = 3.13

Units sold,

x = 3,500

Now,

The total cost will be:

⇒  \bar{y}=\beta_0+\beta_1 x

On substituting the estimated values, we get

⇒     =23,859+3.13\times 3,500

⇒     =23,859+10,955

⇒     =34,814
