Hello!

To solve this equation, we will need to use PEMDAS (parentheses, then exponents, then multiplication/division, then addition/subtraction).

7(3) + (-9) x (-4) =

21 + (-9) x (-4) =

21 + 36 =

I hope this helps you! Have a lovely day!

The men s clothing buyer had a group of 50 jackets priced at $250 each that was selling very slowly. To stimulate sales of these

Answer:

The answer is $3000.

Step-by-step explanation:

The men's clothing buyer had a group of 50 jackets priced at $250 each.

Total price of jackets = $50\times250=12500$ dollars

The buyer reduced the price of the jackets in that group to $200 and 40 jackets were sold.

So, the price for selling 40 jackets is = $40\times200=8000$ dollars

Remaining jackets = $50-40=10$

These were sold at $150 each, totaling to = $10\times150=1500$ dollars

So, overall money earned by reducing prices both time = $8000+1500=9500$ dollars

And the markdown in dollars = (original price before reducing) minus (educed total price)

= $12500-9500=3000$ dollars

So, the answer is $3000.

Answer:

The answer is 8.6×10¹⁴

Step-by-step explanation:

You can evaluate it :

$(4.3 \times {10}^{8} ) \times (2.0 \times {10}^{6} )$

$= (4.3 \times 2.0) \times ( {10}^{8} \times {10}^{6} )$

$= 8.6 \times {10}^{8 + 6}$

$=8.6 \times {10}^{14}$
