Answer:

Step-by-step explanation:    First, let's call the starting elevation of the plane: e

We can then write an equation representing this problem as:    

e−1.5mi=5.25mi

Now, add 1.5mi  to each side of the equation to solve for e

while keeping the equation balanced:

e−1.5mi + 1.5mi=5.25mi + 1.5mi

e−0=6.75mi

e=6.75mi

The plane's starting elevation was 6.75 miles

Eunice lives in indiana, which has a sales tax of 7%. She just bought a couch whose full price was $1200 but she got 20% off bc
Tcecarenko [31]

Answer:

Total amount paid by Eunice=$1,044

Step-by-step explanation:

Step 1: Determine full price of couch

Full price of couch=$1200

Step 2: Determine tax

Tax=tax rate×full price

where;

tax rate=7%

full price=$1200

replacing;

Tax=(7/100)×1,200=$84

Tax=$84

Step 3: Calculate the sale price

Sale price=Full price-20% discount

where;

Full price=$1,200

discount=(20/100)×1,200=$240

replacing;

Sale price=(1,200-240)=960

Sale price=$960

Step 4: Total amount paid by Eunice

Total amount paid by Eunice=Sale price+tax

where;

Sale price=$960

tax=$84

replacing;

Total amount paid by Eunice=(960+84)=$1,044

Total amount paid by Eunice=$1,044

A sales man is paid a basic wage of $225 per week. In addition he is paid a commission of 3% on the value of goods he sells abov
mihalych1998 [28]

Answer:

Commission = $375

Total earnings = $600

Step-by-step explanation:

He gets 3% of any sale he makes above %5500 which means his commission received on this sale is;

= 3% * $12500

= \frac{3}{100} * $12500

= 3* 125

= $375

This means his total earnings for the week will be the basic wage plus his commission

$225 + $375

= $600
