Let antonio's age = a and let sarah's age = s

2a + 3s = 34 (given in question)
s = 5a (given in question)

Because we know that s = 5a, we can replace it with 5a in the first equation to give this:

2a + 3(5a) = 34
∴ 2a + 15a = 34
∴ 17a = 34
∴ a = 2

Therefore we can see that Antonio is 2. Because we have been told that Sarah is 5 times Antonio's age, we can say that Sarah is 10.

Question<br> Translate and solve: Twelve less than x is equal to 51. Enter the equation
mafiozo [28]

Answer:

x = 63

Step-by-step explanation:

From the question, we can deduce the following points;

- 12 less than x which simply means 12 subtracted from x.

- the value of the above expression is equal to 51.

Translating the word problem into an algebraic expression, we have;

x - 12 = 51

Rearranging the equation (collecting like terms), we have;

x = 51 + 12

x = 63

Pete's Convenience Store has a beginning inventory of 12 cans of soup at a cost of $.85 each. During the year, the store purchas
Zepler [3.9K]

A) The number of cans of soup in ending inventory is <u>19.</u>

B) The cost of the ending inventory under LIFO, FIFO, and the weighted average is as follows:

LIFO                                  $17.15

FIFO                                 $25.65

Weighted average          $21.47

<h3>What are the inventory methods?</h3>

The inventory methods include First-in, First-out (FIFO), Last-in, First-out (LIFO), Weighted Average, and Specific Identification.

FIFO assumes that the physical flow of goods during sales follows the chronological sequence of their acquisition.

LIFO assumes that the first goods acquired are the last to be sold.

The Weighted Average uses an average to determine the costs allocated to ending inventory and the cost of goods sold.

Specific Identification identifies the specific goods sold with their costs.

Description                 Units Unit Cost  Total

Beginning inventory     12     $0.85     $10.20

Purchases                      4     $0.95       $3.80

Purchases                      6     $1.05        $6.30

Purchases                      7     $1.35        $9.45

Purchases                     8     $1.50       $12.00

Total                            37                     $41.75

Sales                            18

Ending inventory        19 (37 - 18)

Average cost = $1.13 ($41.75/37)

<u>LIFO</u>:

Ending inventory = $17.15 ($10.20 + $3.80 + 3 x $1.05)

<u>FIFO</u>:

Ending inventory = $25.65 (4 x $1.05 + $9.45 + $12.00)

<u>Weighted Average</u>

Ending inventory = $21.47 (19 x $1.13)
