After w weeks , a student has saved 100 + 15w dollars. How much money has the student saved after 3 weeks ? A$105

B$65

C$120

D$145

D. $145

Step-by-step explanation:

In order to find out the answer to the equation 100 + 15w = ? we have to multiply 15 by the 3 weeks the student has saved up 15 dollars to get the total money they have saved by saving 15 dollars per week:

15 * 3 = 45

we then add the 100 dollars that was already saved up to 45

100 + 45 = $145

So after 3 weeks $145 have been saved up

Hope this helps!!!
