Question

Maria is going school supply shopping. She currently needs 6 spiral notebooks at $4.99 each. She would also like to buy some 3-ring binders. Each binder cost $6.99. She knows her purchase will cost her at least $60; however, she does not want to spend any more than $80. Right and solve an inequality to determine the number of 3-ring binders Maria can buy remain within her budget.

Answer 1

$80 = 6(4.99) + 6.99x$
$80 = 29.94 + 6.99x$
$50.06 = 6.99x$
$7.16 = x$
She can buy 7 3-ring binders
