Equation margaret went shopping with the $100 she got for her birthday. she bought 3 t-shirt’s for $8 each and two pair of jeans for $25 for each. then her mom gave her $25.

100 - 3 x 8 + 2 x 25 + 25

3x8 = 24

2 x 25= 50

50 + 24 = 74

100 - 74 = 26

26 + 25 = 51

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
