kendra is making a large salad for a party. she buys lettuce for $2.25 per pound and tomatoes for $2.65 per pound. she spends at least $8.
let x represent the number of pounds of lettuce that kendra buys. let y represent the number of pounds of tomatoes that kendra buys.
2.25x+2.65y> 8
2.25x+2.65y≥8
2.25x+2.65y< 8
2.25x+2.65y≤8
