A man invests a certain amount a money at 2% interest and $800 more than that amount in another account at 4% interest. At the end of one year, he earned $112 in interested. How many was invested in each account? Which of the following equations could be used to solve the problem?

A. 0.02x + 0.04(800) = 112

B. 0.02x + 0.04(x + 800) = 112

C. 0.04x + 0.02(x + 800) = 112

b i think

step-by-step explanation:

not really sure

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

susie has 7 apples

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
