Ashley is saving money for the newest iPhone. It costs $999.75. She gets a $15 weekly allowance and babysits for 4 hours a week at $13.50 an hour. She gets paid once a week. She pays $4.50 a week for school lunch. She saves the rest of her money. PART A Write an inequality to find the number of weeks it will take her to save enough money for the iPhone.

PART B Solve the inequality.

PART C Graph the solution to the inequality.

PART D How long will it take her to save enough money to buy the iPhone?

A) 999.75 </= 15w + (4(13.5))w - 4.5w

B) 999.75 </= 64.5w

C) Can't Graph On Here Sorry

D) 15.5 weeks

Step-by-step explanation:

A)  999.75 </= 15w + (4(13.5))w - 4.5w

B) 999.75 </= 15w + 54w - 4.5w

999.75 </= 69w - 4.5w

999.75 </= 64.5w

C) Just graph it, Price needed being Y (Also money), Times (in weeks) being X

D) 999.75/64.5

w >/= 15.5

Expressions A, B, and D

Step-by-step explanation:

Expression A works because anything to the power of 0 is equal to one. Therefore, 1/1 = 1.

Expression B works because a negative number that is put to an even-numbered power will end up being positive. Therefore, -1*-1*-1*-1 = 1.

Expression C does NOT work because a negative number that is put to an odd-numbered power will end up being negative (-1*-1*-1*-1*-1*-1*-1 = -1).

Expression D works because positive 1 put to any power will end up being 1, for 1 times itself will end up being 1. Therefore, (you get the idea).

Expression E does NOT work because a number put to a negative power will end up becoming a fraction. 13^-1 is the same thing as writing 1/13. Therefore, 1/(1/13) will equal 13.

Hope this helps!
