Let's set up a system of equations to solve for the unknowns:
Let x = number of cookies sold
Let y = number of lemonades sold
Based on the information given:
1.25x + 1.00y = 51.75
x + y = 45
Now we can use substitution or elimination to solve for x and y.
From the second equation:
x = 45 - y
Substitute x in the first equation:
1.25(45 - y) + 1.00y = 51.75
56.25 - 1.25y + 1.00y = 51.75
0.25y = 4.5
y = 18
Now substitute y back into x = 45 - y:
x = 45 - 18
x = 27
So, Jamal sold 27 cookies and 18 lemonades last week.
Therefore, the correct answer is: 27 cookies and 18 lemonades.
Solve for the unknowns in the following problem: Jamal sells cookies and lemonade for his baseball team’s fundraising event. A cookie is priced at $1.25 each, and lemonade is priced at $1.00 each. Last week, Jamal sold a combined total of 45 cookies and lemonades and collected $51.75. How many of each item did Jamal sell last week?
