Need plz .you have $2500 to invest in two different accounts. in order to save the money you need for college, you need to average 7% interest. if the two accounts pay 7.5% and 6% interest, how much should you invest in each account? round to the nearest dollar amount.

a)$1667 in 7.5%, $833 in 6%

b)$1833 in 7.5%, $667 in 6%

c)$667 in 7.5%, $1833 in 6%

d)$833 in 7.5%, $1667 in 6%

A)$1667 in 7.5%, $833 in 6%

Step-by-step explanation:

You need to average 7% interest.

initial investment = $2500

7% of $2500 = × 2500  ⇒ (0.07 ) × (2500) ⇒ $175

so the combined interest from both accounts should be $175

Checking options:

A)$1667 in 7.5%, $833 in 6%                      ∵ 7.5 % = 0.075  

(1667 × 0.075) + (833 × 0.06)                             6 % = 0.06

125.025 + 49.98 ⇒ 175.005

B) $1833 in 7.5%, $667 in 6%

(1833 × 0.075) + (667 × 0.06)

137.475 + 40.02 ⇒ 177.495

C)$667 in 7.5%, $1833 in 6%

(667 × 0.075) + (1833 × 0.06)

50.025 + 109.98 ⇒ 160.005

D)$833 in 7.5%, $1667 in 6%

(833 × 0.075) + (1667 × 0.06)

62.475 + 100.02 ⇒ 162.495

Option A is the closest to average7% interest of $2500, which is $175.

b. the decimal could be two-tenths.

step-by-step explanation:

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.
