Sam is baking cakes at her parents' bakery. she gets paid $20 a week in addition to $3 for every cake she bakes. she made $80 this week. write an equation to show how many cakes sam baked this week.

3x + 20 = 80

Step-by-step explanation:

If Sam gets paid $20 a week whether she makes any cakes or not, that is a fixed amount.  The amount that she makes will only go up IF she makes cakes.  She makes $3 per cake she bakes, and if the number of cakes is our unknown, the expression for that is 3x.  Adding that to the fixed amount she makes is 3x + 20.  Now we set that equal to 80, which is what she made in a week and solve it for x, which gives us the number of cakes she had to bake to make that $80.

3x + 20 = 80

answer is : muchas/tipicas

have a nice day!
