Answer:

Adriana cared for 40 children, and Brandy cared for 280 children.

Explanation:

Let a = number of children cared for by Adriana.

Let b = number of children cared for by Brandy.

"together they cared for 320 children this week"

a + b = 320

"brandy cared for 7 times as many children as adriana."

b = 7a

a + b = 320

a + 7a = 320

a + b = 320

8a = 320

a + b = 320

a = 40

40 + b = 320

a = 40

b = 280

a = 40

Answer: Adriana cared for 40 children, and Brandy cared for 280 children.
