sam is baking cakes at her parents bakery. she gets paid $20 a week in addition to $4 for every cake she bakes. she made $60 this week. write an equation to show how many cakes sam baked this week

She made 10 additional cakes

Step-by-step explanation:

x = additional cake

20 = base salary

y = 4x + 20

60 = 4(x) + 20

40 = 4(x)

x = 10

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

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
