Answer:

Step-by-step explanation:

p and h are number of plumbers and helpers, respectively.

Twenty workers earn a total of $2600

p+h = 20

h = 20-p

160p + 100h = 2600

160p + 100(20-p) = 2600

60p = 600

p = 10

h = 20-p = 10

Ten plumbers and ten helpers.

Answer:

$P(t)=25,000(1.12)^t$

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

$P(t)=a(b)^t$

where

P(t) is the population in Madison

t is the number of years

a is the initial value

b is the factor of growth

we have

$a=25,000\ people\\b=1.12$

substitute

$P(t)=25,000(1.12)^t$

Vickie made a recipe for 144 fluid ounces of scented candle wax. How many 1 cup candle molds can she fill with the recipe?

jeka57 [31]

There are 8 fluid ounces in 1 cup. You can solve this problem using these proportions:

$\frac{8}{1} = \frac{144}{x}$

It states that there are 8 fluid ounces in every 1 cup and 144 fluid ounces in every x cups. We have to solve for x using cross-multiplication:

$8x = 144 \\ x=18$

Vickie can fill 18 1 cup candle molds with 144 fluid ounces of scented candle wax.
