Answer:
$3000
$1000
Step-by-step explanation:
the formula for simple interest = principal x time x interest rate
let the amount invested in the 2% investment be a
let the amount invested in the 3% investment be (4000 - a)
(a x 0.02 x 1) + ([4000 - a] x 0.03 x 1) = $90
0.02a + 120 - 0.03a = 90
Collect like terms and solve for a
0.01a = 30
a = $3000
The amount invested in the 3% investment be (4000 - a) = $4000 - $3000 = $1000
Answer:
He needs 7/24 cup of milk
Step-by-step explanation:
If he needs 5/8 cup of milk and has 1/3 cup, he will need to subtract so see how much more he needs.
5/8 - 1/3
We need to get a common denominator of 24
5/8 * 3/3 - 1/3 *8/8
15/24 - 8/24
7/24
He needs 7/24 cup of milk
1 out of 16
you multiply 1/4 and 1/4 because that is the probability for each pot and plant
