Question

Leslie bought gifts for each of her 6 friends. She purchased stuffed animals for $2.50 each and keychains for x dollars each. She spent a total of $36.

a) Express the total cost equation: 2.50×6+x=36.
b) Solve for the cost of each keychain (x).
c) If the keychains cost $5 each, how much did Leslie spend in total?

Answer 1

The total cost equation is 2.50*6 + x = 36. To find the cost of each keychain (x), subtract 2.50*6 from 36. If the keychains cost $5 each, Leslie spent a total of $21.

Step-by-step explanation:

To express the total cost equation, we can use the equation 2.50*6 + x = 36, where x represents the cost of each keychain.

To solve for x, we can subtract 2.50*6 from both sides of the equation:

x = 36 - 2.50*6

Finally, to find out how much Leslie spent in total when the keychains cost $5 each, we can substitute x with 5 in the equation:

Total cost = 2.50*6 + 5 = $21
