Question

Jessies daughter went to target and bought $1 or $2 items from the one spot area. She wants to spend less then 20$ at target. Part A: List three possiable combinations of $1 or $2 items she could buy. Part B: Write an inequality to represent the situation. Part D: What is the difference between the ordered pairs that fall on the line and the ones that fall in the shaded area?

Answer 1

Explanation:

part A:

she can buy 8 of $1 items and and 5 $2 since

`8(1) + 5(2)= 8 +10 =` $18 < $20

she can buy 5 $1 items and and 7 $2 since

`5(1) + 7(2)= 5 +14 =` $19 < $20

she can buy 5 $3 items and and 8 $2 since

`3(1) + 8(2)= 3 +16 =` $19 < $20

part B:

let x represent $2 and y represent $1 , since she wants to spend below $20 this would be

`2x +y<20`

part C:

refer to the attached graph for part c

the difference between the ordered pairs that falls on the line and the shaded area is 0
