Theodore invests a total of $17,500 in two accounts paying 2% and 12% annual interest, respectively. How much was invested in ea
iVinArrow [24]

Answer:

11,500 at 2% and $6,000 at 12%.

Step-by-step explanation:

Let x represent amount invested at 2% and y represent amount invested at 12%.

We have been given that Theodore invests a total of $17,500 in two accounts. We can represent this information in an equation as:

x+y=17500...(1)

x=17500-y...(1)

We are also told that he invested $17,500 in two accounts paying 2% and 12% annual interest, respectively. After one year, the total interest was $950.00.

Interest earned at 2% in one year would be 0.02x.

Interest earned at 12% in one year would be 0.12y

0.02x+0.12y=950...(1)

Upon substituting equation (1) in equation (2), we will get:    

0.02(17500-y)+0.12y=950

350-0.02y+0.12y=950

350+0.10y=950

350-350+0.10y=950-350

0.10y=600

\frac{0.10y}{0.10}=\frac{600}{0.10}

y=6000

Therefore, Theodore invested $6,000 at 12%.

Upon substituting y=6000 in equation (1), we will get:

x=17500-6000

x=11500

Therefore, Theodore invested $11,500 at 2%.

Determine the whether the sum of 7/8 and 4/9 is closest to 0,1,2,or 3
elena55 [62]
Whenever you add fractions it means you need a common denominator. The quickest way to find this number is to multiply the two denominators together (in this case 8 and 9).
So your new fractions are 63/72 and 32/72. When you add those you get 95/72.
Next simply divide the two numbers to get a decimal, so here we get: 1.31944...
So this number is closer to 1
Hope that helps!!
