Lilly and Samuel purchased supplies together for a school project. They need to determine how much each person should pay.
Markers cost $2.59 each
Poster boards cost $5.59 each
Glue sticks cost each.
Lilly selects 5 markers and 2 poster boards and a glue stick. Samuel selects 3 markers and 3 poster boards and a glue stick. The total for their combined purchase was $49.57.
First, select the equation that could be used to solve for x, the cost of one glue stick. Then, select the amount that each person should pay based on the supplies they selected.
The equation that could be used to solve for x, the cost of one glue stick, is:
5(2.59) + 2(5.59) + x = 49.57
To solve for x, we multiply the cost of the markers and poster boards by the quantities selected, and then subtract the total from the combined purchase of $49.57.
Next, we can calculate the total cost for each person based on the supplies they selected:
Lilly's total cost = 5(2.59) + 2(5.59) + x (cost of glue stick)
Samuel's total cost = 3(2.59) + 3(5.59) + x (cost of glue stick)
