K= 100

You use distributive property

Step 1: −(−k)−1(−86)+10=−4

Step 2: k−1(−86)+10=−4

Step 3: k+86+10=−4

Step 4: k+96=−4

Step 5: k=−96−4

Step 6: Subtract 4 from −96 to get −100.

Swimming Pool On a certain hot summer's day, 253 people used the public swimming pool. The daily prices are $ 1.50 for children

e-lub [12.9K]

Answer:

Therefore 164 children and 89 adults swam at the public pool that day.

Step-by-step explanation:

Given that,

253 people used the public swimming pool.

The daily prices for children are $1.50 and for adults are $2.25.

Let the number of children be x.

Then number of adult is (253-x)

The total money collect on that day is $=\$[(1.50\times x)+2.25(253-x)]$

$=\$[1.50x+569.25-2.25x]$

$=\$[569.25-0.75x]$

According to the problem,

$569.25-0.75x=446.25$

$\Rightarrow -0.75 x=446.25-569.25$

$\Rightarrow -0.75 x=-123$

$\Rightarrow x=\frac{123}{0.75}$

$\Rightarrow x=164$

Therefore 164 children and (253-164)=89 adults swam at the public pool that day.

Assume the reserve requirement is 10%. First National Bank receives a deposit of $5,400. If there is no slippage, how much could

d1i1m1o1n [39]

Given:

Reserve requirement = 10%
Deposit = $5400

Find:

money the supply could expand = ?

Solution:

Money Supply = Monetary Base × Money Multiplier

Before we determine the money supply, the money multiplier must already be determined. Therefore:
$5400 (0.10) = $540

In this case, adding the two will give us the money supply
$5400 + $540 = $5940

Nevertheless, not all money is lent out or spent. Kept money reduces the money supply.

The restrain to the growth of the money supply when deposits expand are identified by 2 factors:

1. The amount above (excess reserves) what they are required to hold are being kept.

2. Their income rises as the public has the penchant to hold more cash as their income.
