You have 550$ in a savings account that earns 3% simple interest each year.How much will be in your account in 10 years?
Tomtit [17]
Hey there! Hope I can help!

<span><span>P is the principal amount, $550.00.
</span><span>R is the interest rate, 3% per year, or in decimal form, 3/100 = 0.03.
</span><span>T is the time involved, 10 year(s) time period.
</span><span>So, t is the 10 year time period.

</span></span><span>To find the simple interest, we multiply 550 × 0.03 × 10 to get $165.00
</span>
<span>Then the interest is added onto the principal to figure the new amount after 10 years. </span>
<span>550.00 + 165.00 = 715.00 > $715.00 after 10 years.</span><span>

Hope this helps!

Veronika [31]

Answer: 9x+y=-6

Step-by-step explanation:

Standard: Ax+By=C

y=-9x-6

We need -9x on the left side, to move it, we must add 9x on both sides.

9x+y=-9x-6+9x\\9x+y=-6

Done. We have Ax = 9x, By = 1y and C after the equal sign = -6
