A bag contains purple marbles and green marbles, 55 in total. The number of purple marbles is 7 more than 2 times the number of
kirill [66]

There are 39 purple marbles in the bag

Step-by-step explanation:

The given is:

  • There are 55 purple and green marbles in total in a bage
  • The number of purple marbles is 7 more than 2 times the number of green marbles

We need to find how many purple marbles in the bag

Assume that the number of the purple marbles is P and the number

of the green marbles is G

∵ There are P purple marbles and G green marbles in the bag

∵ There are 55 marbles in the bag

∴ P + G = 55 ⇒ (1)

∵ The number of purple marbles is 7 more than 2 times the number

   of green marbles

- Add 7 and 2 times G to get P

∴ P = 7 + 2 G

- Subtract 2 G from both sides

∴ P - 2 G = 7 ⇒ (2)

Let us solve the system of equations to find P

Multiply equation (1) by 2 to eliminate G

∵ 2 P + 2 G = 110 ⇒ (3)

- Add equations (2) and (3)

∴ 3 P = 117

- Divide both sides by 3

∴ P = 39

∵ P represents the number of the purple marbles in the bag

∴ There are 39 purple marbles in the bag

There are 39 purple marbles in the bag

kvasek [131]

Answer:

April Beginning Balance $ 1,633,427

Step-by-step explanation:

The closing balance of January is the opening balance of February

February,

Opening Balance $1,234,567

Add Payment received on invoices $825k

Less Cost of sales $198k,

Less Overheads $356k ,

Less Other Expenses $92k .

February Ending Balance $ 1,413, 567

March

Beginning Balance $ 1,413, 567

Add Payment received on invoices $825k *1.12= 924 k

Less Cost of sales $198k *1.09= 215.82k

Less Overheads $356k *1.09= 388.04k

Less Other Expenses $92k *1.09= 100.28k

March Ending Balance = $ 1,633,427

April Beginning Balance $ 1,633,427

Treating the Costs of Sales, Overheads and the other expenses as the expenses paid out of the Bank Balance meaning no accounts payable or other cash paid.
