A store sells cans of paint for $8 each, and brushes for $12 each. If they sell 100 items, and

Montano1993 [528]

Answer:

B.) 80 cans, 20 brushes

Step-by-step explanation:

Let the cans of paint be represented by variable p , and brushes by variable b

The first equation would be ; p + b = 100

p = 100 - b

The second equation would be;

8p + 12b = 880

Replace p in the equation by (100-b);

=8(100-b) + 12b =880

=800 - 8b +12b = 880

= subtract 800 from both sides to get;

4b = 880-800

4b = 80

divide both sides by 4 to solve for b;

b= 80/4

b = 20

If p + b = 100, then p+20 = 100

p = 100-20

p = 80

Therefore, they sold 80 cans of paint and 20 brushes

QUESTIONS The average price of wheat per metric ton in 2012 was $30575. Demand in millions of metric tons) in 2012 was 672. The

soldi70 [24.7K]

Answer: -0.9 ; inelastic

Explanation:

Given:

The average price of wheat per metric ton in 2012 = $305.75

Demand (in millions of metric tons) in 2012 = 672

The average price of wheat per metric ton in 2013 = $291.56

Demand (in millions of metric tons) in 2013 = 700

We will compute the elasticity using the following formula:

ε = $\frac{\frac{(Q_{2} - Q_{1})}{\frac{(Q_{2} +Q_{1})}{2}}}{\frac{(P_{2} - P_{1})}{\frac{(P_{2} +P_{1})}{2}}}$

ε = $\frac{\Delta Q}{\Delta P}$

Now , we'll first compute $\Delta Q$

i.e. $\frac{\Delta Q}{\Delta P}$ = $\frac{(700 - 672)}{\frac{(700 +672)}{2}}$

$\Delta Q$ = 0.04081

Similarly for $\Delta P$

i.e. $\Delta P$ = $\frac{(291.56 - 305.75)}{\frac{(261.56 +305.75)}{2}}$

$\Delta P$ = -0.0475

ε = $\frac{0.04081}{-0.0475}$

ε = -0.859 $\simeq$ -0.9

$\because$ we know that ;

If, ε > 1 ⇒ Elastic

ε < 1 ⇒ Inelastic

ε = 1 ⇒ unit elastic

$\because$ Here , ε = -0.859 $\simeq$ -0.9

Therefore ε is inelastic.

Claire is painting some doors that are all the same size. She used 2 liters of paint to cobe 1 3/5 doors. How many liters of pai

Deffense [45]

Answer:

$1 \dfrac{1}{4} \ liters$

Step-by-step explanation:

Given that:

Claire uses 2 liters of paint to cover 1 3/5 doors

Then in order for her to paint 1 door, She will need:

2 L = 1 3/5 door

x L = 1 door

$x (L) = \dfrac{2 L \times 1 door }{ 1 \dfrac{3}{5} \ door}$

$x (L) = \dfrac{2 L }{ 1 \dfrac{3}{5} }$

$x (L) = \dfrac{2 L }{ \dfrac{8}{5} }$

$x (L) = \dfrac{2 L\times 5 }{ 8 }$

$x (L) = \dfrac{10 \ L }{ 8 }$

$x(L) =1 \dfrac{1}{4} \ L$
