fabiana decides to save the money she is earning from her after school job for college. she makes an initial contribution of 300

Oxana [17]

Answer:

A. Total Money Contributed after n months = $\$ 3000 + \$ (500\times n)$

B. Total Money Contributed after 24 months = $\$ \ 15000$

Step-by-step explanation:

Given:

Initial contribution = $\$\ 3000$

each month contribution = $\$\ 500$

After 1 month contributed = $\$\ 3000 + \$\ 500 \times 1= \$ \ 3500$

Solving for Part A

let n be the number of months

∴ Total Contribution after n months = Initial contribution + (each month contribution $\times$ Number of months = $\$\ 3000 + \$\ 500 \times n$

Solving for Part A

Now n= 24 months

∴ Total Contribution after 24 months = $\$\ 3000 + \$\ 500 \times 24 = \$\ 3000 + \$\ 12000= \$\ 15000$

Answers? with explanations

Alinara [238K]

Okay, so basically we have:
w as width; and 6+w as length

Perimeter=2w+2l

just substitute it with the values of width and length

P=2w+2(6+w)
P=2w+12+2w
P=4w+12

So, the answer is letter B.
