Ответ:
is the total cost where x is number of combined red and orange beads and y is combined pink, yellow, and purple beads.
Step-by-step explanation:
We are given the following in the question:
Cost of combined red and orange beads = $0.50 per 12 beads
Cost of combined pink, yellow, and purple beads = $1.50 per 8 beads
Discount amount = $5
Let x be the number of combined red and orange beads and y be the number of combined pink, yellow, and purple beads.
Then, we can write the cost function as:
Total cost =
Cost of red and orange beads + Cost of pink, yellow, and purple beads - Discount
is the required total cost of Melissa's order.
