two customers went to a post office to buy postcards and envelopes. Each postcard costs the same amount, and each large envelope

Mariulka [41]

Answer:

The cost of postcard is $0.122 and the cost of large envelope is $1.57.

Step-by-step explanation:

Let, the cost of postcards = x and the cost of large envelopes = y.

According to the question, we get the following system of equations,

34x + 5y = 12

10x + 15y = 24.80

We will now solve this system to obtain the value of x and y.

First, we divide second equation by 5,

34x + 5y = 12

2x + 3y = 4.96

Now, we multiply second equation by 17,

34x + 5y = 12

34x + 51y = 84.32

Subtracting the equations gives us,

-46y = -72.32 i.e. y = 1.57.

Substituting the vale of y in the first equation gives us,

34x + 5 × 1.57 = 12 i.e. 34x + 7.85= 12 i.e. 34x = 4.15 i.e. x = 0.122.

Hence, the cost of postcard is $0.122 and the cost of large envelope is $1.57.

The bakers at Healthy Bakery can make 170 bagels in 2 hours. How many

Maru [420]

Given:

The bakers at Healthy Bakery can make 170 bagels in 2 hours.

To find:

How many bagels can they bake in 14 hours and the rate per hour.

Solution:

We have,

Number of bagels the bakers can bake in 2 hours = 170 bagels

Number of bagels the bakers can bake in 1 hours = $\dfrac{170}{2}$ bagels

= 85 bagels

Therefore, the average rate is 85 bagels per hour.

Number of bagels the bakers can bake in 14 hours = $14\times 85$ bagels

= 1190 bagels

Therefore, the bakers can bake 1190 bagels in 14 hours.
