Answer:
$11,600
Step-by-step explanation:
amount loaned at 8% and ($12,000 - x) = amount loaned at 18%
Write the equation: (change the percents to decimals: 8% = 0.08 and 18% = 0.18)
(0.08)x + (0.18)($12,000 - x) = $1,000
This expresses the total amount of earned interest in terms of the amounts of the loan, x and ($12,000 - x}.
0.08x + $2,160 - 0.18x = $1,000 Simplify and solve for x.
-0.1x = -$1,160 Divide both sides by -0.1
x = $11.600 The amount loaned at 8% interest.
640. the answer would be 640
Answer:
x = 8
Step-by-step explanation:
Given
5x + 6 = - 10 + 7x ( subtract 7x from both sides )
- 2x + 6 = - 10 ( subtract 6 from both sides )
- 2x = - 16 ( divide both sides by - 2 )
x = 8
Answer:
3 batches
Step-by-step explanation:
You know that he has a total of
of chocolate chips and to make one batch, he uses
of those chocolate chips. Another way of looking at it would be in this example, say I have a total of 10 balloons and I give 2 balloons to each person who visits me. How many people would get balloons? The answer would be 5 as I divide the total number of balloons that I have by 2. Similarly:
÷
×6
3
