A store manager is buying new helmets and new skateboards. The manager has at most $1,200 to spend. Each helmet costs $25 and each skateboard costs $80. The manager wants to buy at least as many helmets as skateboards. If x is the number of helmets and y is the number of skateboards, which of the following systems of inequalities represents this situation?

A

$25x+80y\ge 1200$
$x\le y$

B

$25x+80y\le 1200$
$x\le y$

C

$25x+80y\le 1200$
$x\ge y$

D

$80x+25y\le 1200$
$x\ge y$
