I would say that it might be B, or C, by looking at it a bit more
Answer: 13 cats were at the shelter on Thursday.
Step-by-step explanation:
Let x represent the number of cats that were at the shelter on Thursday.
Let y represent the number of dogs that were at the shelter on Thursday.
Camden found a record showing that there were a total of 30 cats and dogs on Thursday. This means that
x + y = 30
The animal shelter spends $2.50 per day to care for each cat and $4.00 per day to care for each dog. Camden noticed that the shelter spent $100.50 caring for cats and dogs on Thursday. This means that
2.5x + 4y = 100.5 - - - - - - - - - - - - 1
Substituting x = 30 - y into equation 1, it becomes
2.5(30 - y) + 4y = 100.5
75 - 2.5y + 4y = 100.5
- 2.5y + 4y = 100.5 - 75
1.5y = 25.5
y = 25.5/1.5
y = 17
x = 30 - y = 30 - 17
x = 13
answer:
22 weeks
step-by-step explanation:
- set up a proportion
- use x for how long it would take her
- cross multiply to solve
39 / 2 = 429 / x
429 (2) = 39x
858 = 39x
x = 22
- it would take her 22 weeks
- you can change the units by conversion based on what is asked
You take how many shirts she sold and then multiply it by the cost of one shirt.
Therefore, you do 39 shirts * $16.50, which is equal to $643.50 in revenue :)
