Answer: Total costs for 49 baskets = $300
She make 145 dessert baskets the week before.
Step-by-step explanation:
Given : Fixed weekly costs for rent and electricity = $200
The ingredients for one dessert basket costs = $2.50
Let x be the number of baskets made by Casey, then the total weekly cost will be :-
Total weekly costs = Fixed weekly cost + Cost of ingredients for one dessert × x
= 200+2.5x
For x= 40
Total weekly costs = $200+$2.5(40)=$200+$100=$300
i.e. Total costs for 49 baskets = $300
Her total costs for the week before 562.50.
i.e. [tex]562.50= 200+2.5x[/tex]
Subtract 200 from both sides.
[tex]362.50=2.5x[/tex]
Divide 2.5 from both sides.
[tex]x=\dfrac{362.50}{2.5}=145[/tex]
Hence, she make 145 dessert baskets the week before.
