PLEASE HELP !!!!!!!!?!!!!!!!

Answer 1

Answer:

200 is the number of sandals

500 is the number of shoes

Step-by-step explanation:

x is the number of sandals

y is the number of shoes

so 2.5x + 4y = 2500

=> x = (2500 - 4y)/2.5

In the month of April, the numbers of shoes doubles

2.5(2x) + 4y = 3000

5x + 4y = 3000

Substitute x = (2500 - 4y)/2.5

5(2500 - 4y)/2.5 + 4y = 3000

5000 - 8y + 4y = 3000

-4y = - 2000

y = 500

x = (2500 - 4y)/2.5 = (2500 - 4(500))/2.5

x = (2500 - 2000)/2.5

x = 500/2.5 = 200
