Compound interest is the starting amount x (1+ the interest rate as a decimal)^ the time in years=the final amount.

In your case, the equation will be $1000*(1+0.10)^how many years= the final amount.

Nesterboy [21]

<u>Complete Question</u>

The table shows the number of grade 7 and grade 8 students on the student council at Jeremy’s school.

Number of Students

  • Grade 7 - 17
  • Grade 8 - 34

Answer:

C- The number of outcomes representing each grade level does not change after the first student is chosen.

Step-by-step explanation:

The ratio of Grade 7 students to Grade 8 students is:

17:34

This written in reduced form is 1:2

Therefore, initially, the six parts of the cube can be divided into the ratio 2:4 which Jeremy did.

However, after the first selection of a student, the ratio of Grade 7:Grade 8 student changes since the same student cannot be chosen more than once.

Therefore the cube rolls represent only the first student choice and may not be accurate for subsequent rolls.

The correct option is C.

Luba_88 [7]

Answer: (A) The number is 14

(B) Lily is 16 years old

(C)The number is 35

(D) The wallet cost $20

Step-by-step explanation: (A) Let the number be a. Three times the number is equal to 3 times a, or 3a. Seven more than 3a equals 49, that means

7 + 3a = 49

Subtract 7 from both sides of the equation

3a = 42

Divide both sides of the equation by 3

a = 14

The number is 14

(B) Let Hillary's age be h and Lily's age be l, so if Hillary's age is 3 years greater than Lily's age, then we have

h = 3 + l

Then if Hillary's age is now given as 19, the equation becomes

19 = 3 + l

Subtract 3 from both sides of the equation

16 = l

Lily's age is 16

(C) Let the number be x, and so twice the number becomes 2 times x which is 2x. Twice the number decreased by 20 is 50, becomes

2x - 20 = 50

Add 20 to both sides of the equation

2x = 70

Divide both sides of the equation by 2

x = 35

The number is 35

(D) Let each handbag be represented by b and each wallet be represented by w. The cost of each handbag is 10 more than the wallet, so if the wallet cost w, then the handbag would cost w + 10. This can be expressed as

h = w + 10

If she spent a total of 60 for the 2 handbags, then each handbag would cost 60 ÷ 2 which equals 30 per handbag. Substituting for the known value we now have,

30 = w + 10

Subtract 10 from both sides of the equation

20 = w

The cost of a wallet is $20
