Solving/Interpreting Linear Inequalities in Two Variables

Write the linear inequality in standard form for this situation: Ms. Savva is ordering pizzas and breadsticks for a school party and has a budget of no more than RM81. An order of breadsticks costs RM7 and a pizza costs RM13.

• 7x + 13y < 81

• 7x + 13y ≤ 81

• 7x + 13y ≥ 81

• 7x + 13y > 81

Which inequality matches the picture shown?

• y < -1/2 x + 5

• y > -1/2 x + 5

• y < -1/2 x + 5

Yumi is determining the seating arrangement for her big dinner party. Circular tables will seat 8 guests and rectangular tables can seat 10 guests. Yumi is informed that at least 162 guests are attending. Write an inequality that describes the situation. Let x = # of circular tables Let y = # of rectangular tables

• 8x + 10y < 162

• 8x + 10y ≤ 162

• 8x + 10y > 162

• 8x + 10y ≥ 162

Which scenario fits this graph best?

• You have RM20 to spend. Hotdog cost RM5 and hamburger cost RM2. How many hotdogs and hamburgers can you buy?

• You have RM30 to spend. Hotdog cost RM5 and hamburger cost RM3. How many hotdogs and hamburgers can you buy?

• You have RM20 to spend. Hotdog cost RM4 and hamburger cost RM10. How many hotdogs and hamburgers can you buy?

• You have RM30 to spend. Hotdog cost RM5 and hamburger cost RM6. How many hotdogs and hamburgers can you buy?
