At the high school band's annual spaghetti dinner, the members served 210 dinners and collected $935. The band leader did not de

Jlenok [28]

Answer:

935 = 6a + 3.5c (this is the amount that has been raised)

210 = a + c (this is this amount of the dinners being sold)

Step-by-step explanation:

so a = 210 - c

935 = (6 * (210 - c)) + 3.5c

6 * 210 is 1260, so:

935 = 1260 - 6c + 3.5c

2.5c = 1260 - 935

2.5c = 325

so c = 130

a = 210 - 130 = 80

We know that 80 adult dinners were sold.

We also know 130 child dinners were sold as well.
