Im checking my test. whats the answer?

C.

Hope this helps. :)))

C

Step-by-step explanation:

It can' be B because as you go right on the x-axis (forward in time), the distance upward on y (how far walked) also goes up steadily. So that is a person walking at a steady pace, no stopping.

A is interesting.  It shows the person walked in the positive y-direction, stopped a while, and then went back the other way (negative y-direction).

C shows a person walking (in the positive y-direction), then stopping, then walking in the same direction some more. The probelm says they walk slower after the pause, so the slope on the second part should be less steep. I guess it is, but would it have killed them to make it a little more obvious? haha.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
