It would be 3, 3 + 51= 54, which is even, meaning it counterexamples the conjecture that 3 plus any number is odd.

Nadia is a stockbroker. She earns 12% commission each week. Last week, she sold $5400 worth of stocks. How much did she make las
Inga [223]

Answer:

a). Nadia made a total of $825 last week in commission sales

b). The total amount Nadia in commission in 2011=$42,900

Step-by-step explanation:

Step 1

Express the amount in commission she earns from her sales as follows;

C=S×r

where;

C=commission earned

S=total value of stock sales

r=commission rate

In our case;

C=unknown

S=$7,500

r=11%=11/100=0.11

replacing;

C=11% of 7,500

C=(11/100)×7,500

C=0.11×7,500=825

Nadia made a total of $825 last week in commission sales

b). To express the total amount she made in 2011, we derive the formula below;

Total amount (2011)=Average weekly commission×number of weeks in 2011

where;

Average weekly commission=$825

number of weeks in 2011=52

replacing;

Total amount (2011)=(825×52)=42,900

The total amount Nadia in commission in 2011=$42,900

David has a loyalty card good for a 19% discount at his local hardware store. What would his total in dollars and cents be, afte
Elina [12.6K]

Discounts are used to reduce the original price of an item.

David will pay $25 and 92 cents for an item of $32, before tax

The discount (d) is given as:

d =19\%

The price (p) of the item is given as:

p = \$32

So, the amount (A) paid before tax is calculated using:

A = p \times (1 - d)

Substitute known values

A = \$32 \times (1 - 19\%)

Express percentage as decimal

A = \$32 \times (1 - 0.19)

Subtract 0.19 from 1

A = \$32 \times 0.81

Multiply 32 and 0.81

A = \$25.92

Hence, David will pay $25 and 92 cents for an item of $32, before tax

What two numbers add to make 36 with one of the numbers being exactly twice the other?
11111nata11111 [884]

Answer:

12 and 24

Step-by-step explanation:

2 numbers, x in this case, with one being twice the other, one of them will be 2x, equals 36. Your equation would look like this: 2x+x=36. Simplify it to get 3x=36, divide the 3 and you get 12. 12 will be your small number then multiply by 2 to get your large one, 24.
