the Spanish club is selling churros as a fundraiser. If its goal is to raise at least $150, how many churros must it sell at $1.25 each to meet that goal? write and solve an inequality.
Let the number of churros sold be x, then
1.25x ≥ 150
x ≥ 150/1.25
x ≥ 120
Let
x-------> the number of churros sold
we know that
\(1.25x \geq 150\) -----> inequality that represent the situation
Solve for x
Divide by \(1.25\) both sides
\(x \geq 150/1.25\)
\(x \geq 120\ churros\)
therefore
the answer is
The minimum number of churros that must be sold is \(120\)
