Answer:
225 + 63n for n- a natural number,
set 512=225+63n to find total number of weeks
63=21*3
use n=4 to solve the amount saved in 4 weeks
they wont 60*4=240, 240+12, 252+225=477
how much are the saving a day
what do they need to put up to have enough in 4 weeks
how much a day do the need to save to go in 1 week
etc
Step-by-step explanation:
Answer:
9/60
Step-by-step explanation:
Sample Response/Explanation: To find the experimental probability, compare the total number of times the event occurs to the total number of trials. Compare the frequency of rolling the number six (9) to the total number of trials (60) using a ratio, and then reduce.
Part A
We have x = 4 and y = 3 paired up together.
This says that 4 pounds of potatoes cost $3
The price per pound (aka unit price) is y/x = 3/4 = 0.75 dollars = 75 cents.
Answer: 75 cents per pound
========================================
Part B
The ordered pair (8,6) means x = 8 and y = 6 pair up together.
So in this case, 8 pounds of potatoes cost $6.
notice how y/x = 6/8 = 3/4 = 0.75 dollars = 75 cents here as well. So we get the same unit cost.
