An animal shelter spends $3.50 per day to care for each bird and $6.50 per day to care for each cat. Brooklyn noticed that the s

Vikki [24]

Solution: Let $x$ be the number of birds and $y$ be the number of cats.

$x+y=29 \implies y=29-x$

$3.50 x +6.50 y= 146.50$

$3.50 x+6.50(29-x)=146.50$

$3.50x+188.5-6.5x=146.50$

$3x=188.5-146.50$

$3x=42$

$x=\frac{42}{3} =14$

Therefore, there were 14 birds at the shelter on Friday

kramer

Answer:

9 tapes

Step-by-step explanation:

First, subtract the handling charge from his $78.

78 - 3.50 = 74.5

So, Brian has $74.50 to purchase tapes. Each tape costs $7.50, so let's find out how many he can purchase.

74.50 / 7.50 = 9.933 (approximately)

Since Brian can't buy 0.933 of a tape, he will only be able to buy 9 tapes.
