It cost $15 for 5 packs of baseball cards how much will it cost to buy 25 packs of baseball cards (answer in proportion)

$75

Step-by-step explanation:

Since 5 packets of baseball cards cost $15 so if we divide $15 by 5, we will get $3 as the cost of 1 baseball card , now multiply it by 25 to get the cost of 25 packs.

y=7

Step-by-step explanation:

Using the formula: (y - y1) = 0 (x - x1)

Substitute x1 with -2, and y1 with 7 and set the slope as 0.

Y-7=0(x-(-2))

Y - 7 = 0 (x + 2)

Anything times 0 = 0, so cancel out the -2.

Y-7=0

Add the 7 to the 0.

Y = 7
