On Saturday, their lane rentals were down by StartFraction 1 over 8 EndFraction but the concessions increased by One-half. What is the total amount that the bowling alley earned in lane rentals and concessions on Friday and Saturday? $1,355.95
$1,580.10
$1,992.48
$2,611.05

  $2611.05

Step-by-step explanation:

  earnings = lane rentals + concessions

Friday:

  earnings = $842.72 +412.38 = $1255.10

Saturday:

We assume "down by 1/8" means the value was 1 -1/8 = 7/8 that of the previous day. Likewise, "increased by 1/2" is assumed to mean the value was 1 + 1/2 = 3/2 that of the previous day.

  earnings = 7/8×$842.72 + 3/2×412.38 = $1355.95

__

Then the total earnings for both days were ...

  $1255.10 +$1355.95 = $2611.05
