You are planning to purchase ten pencils of type A which cost a total of $14.00 and five pencils of type B which cost $15.00. A) what is the price unit of each type per pencils? B) which is a better buy?

A.1 type A pencil costs $1.40. 1 type B pencil costs $3.00.

B. Type A pencils are a better buy.

Step-by-step explanation:

A.14.0 divided by 10 is 1.4. 15.0 divided by 5 is 3.

B. 10 type b pencils cost $30.00. 10 type a pencils cost less, only $14.00, so it is a better buy. Hope this helped!

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
