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.
Answer:
11/5 inches
Step-by-step explanation:
total snowfall for the day = snowfall in morning + snowfall in evening
= 8 over 5 + 3 over 5 (all in inches)
= 8/5 + 3/5 (all in inches)
Since the denominators are the same (5), we can simply add the numerators up while keeping the denominator
(8/5 + 3/5) inches= (8+3)/5 inches = 11/5 inches = total snowfall for the day
