If Shipping in my store is Total cost = Cost per item + $5 shipping
Total cost = ($price per item$ * x) + $5
And Shipping at a different place is Total cost = Cost per item + $20 shipping
Total cost = ($0.5 * price per item * x) + $20
from whom should she buy? Explain your answer.
She should buy from the store with the lower total cost. In this case, if we plug in values for $price per item$ and x, we can see which store offers the lower total cost.
For example, if $price per item$ = 10 and x = 1:
- Store 1: Total cost = ($10 * 1) + $5 = $15
- Store 2: Total cost = ($0.5 * 10 * 1) + $20 = $25
In this scenario, it is cheaper to buy from Store 1 because the total cost is lower. Therefore, she should buy from the store with the lower total cost, which may vary based on the specific prices and quantities purchased.
