Last year, Maria had $10,000 to invest. She invested some of it in an account that paid 6% simple interest per year, and she inv
denis-greek [22]

Answer:

$3,000 invested at 6%

$7,000 invested at 10%

Step-by-step explanation:

Maria had total $10,000 to invest.

Let x be the amount that Maria invested initially at 6% interest rate.

0.06x

Then she invested the remaining amount at 10% interest rate.

0.10(10,000 - x)

She received a total of $880 in interest.

0.06x + 0.10(10,000 - x) = 880

0.06x + 1000 - 0.10x = 880

-0.04x = 880 - 1000

-0.04x = -120

0.04x = 120

x = 120/0.04

x = $3,000

This is the amount that Maria invested initially at 6% interest rate.

The remaining amount is

10,000 - 3,000

$7,000

This is the remaining amount that she invested at 10% interest rate.

<h2><em><u>3</u></em></h2>

Step-by-step explanation:

<h3><u>Given</u><u> </u><u>question</u><u>:</u></h3>

<em>To</em><em> </em><em>simplify</em><em> </em><em>-</em><em> </em>

14 + 16 \div  {2}^{3}  - (12 +  {3}^{2} ) \div 7 + 2 \times ( - 5)

<h3><u>Solution</u><u>:</u></h3>

<em>According</em><em> </em><em>to</em><em> </em><em>PEMDAS</em><em> </em><em>rule</em><em>,</em>

  • <em>[</em><em>First</em><em> </em><em>parenthesis</em><em>]</em>

= 14 + 16 \div  {2}^{3}  - (12 +  9 ) \div 7 + 2 \times ( - 5)

= 14 + 16 \div  {2}^{3}  - 21 \div 7 + 2 \times ( - 5)

  • <em>[</em><em>Then</em><em> </em><em>exponents</em><em>]</em>

= 14 + 16 \div  8  - 21 \div 7 + 2 \times ( - 5)

  • <em>[</em><em>Then</em><em> </em><em>multiplication</em><em>]</em>

= 14 + 16 ÷ 8 - 21 ÷ 7 - 10

  • <em>[</em><em>Then</em><em> </em><em>division</em><em>]</em>

= 14 + 2 - 3 - 10

  • <em>[</em><em>Then</em><em> </em><em>addition</em><em>]</em>
