Math Inequalitys

Question

1. Lori has $75 to spend on clothes. She wants to keep $5.00 for ice cream and she wants to buy a pair of jeans for $15.00. She will spend what is left on t-shirts. Each t-shirt costs $5.50. Write an inequality to represent the number of shirts she can purchase. How many shirts can she purchase?

Answer 1

s= (1/5.5)(75-5-15)

= 55/5.5

= 10 shirts

or if you want an inequality, then

s</= 10

# of shirts possible to buy on that budget is less than or equal to ten

at $5.50 per shirt, costing total $55, $20 on ice cream & jeans
