Given that Noemi makes a bracelet that averages $0.60 per bead, we need to write an equation that models this average bead cost. This can be found by taking the total cost of the beads and dividing it by the number of beads used.
1. The total cost of the beads may be found by multiplying the price of each type of bead by the number used, and then adding these values together. Thus:
Total Cost = 0.75x + 3*0.3
= 0.75x + 0.9
2. Total number of beads = x + 3
3. Thus, the average cost is:
(0.75x + 0.9)/(x + 3)
4. Using the value of the average cost per bead given to us ($0.60), we can now write up the full equation:
0.6 = (0.75x + 0.9)/(x + 3)
Divide the total cost by the number of games bought. The store with the lowest amount is the better buy.
Store A : 8.36/2 = $4.18 each game
Store B: 12.84/3 = $4.28 each game
Store A has the lower price per game so Store A has the better deal.
Answer:
When did Mary and Wyatt meet? 0.5 minutes later
How far from point Q did they meet? 3.5 km
Step-by-step explanation:
Mary’s motion is represented by d = 8t----(1)
Wyatt’s motion is represented by 2d + 14t = 15----(2)
We solve for d in equation (2) to get:d=7.5-7t----(3)
We equate equation (1) and (3) to get:
We now solve for t to get:
Now put t=0.5 into equation (1) to get d=0.5*8=4
This means they met 4 km from point P.
Therefore they meet 7.5-4=3.5km from point Q
