What would be the answer to this question and how would you solve it? ?

it is #24

the slope is the change in Y over the change in x

 x = the first numbers 5 & 10

y = the second numbers 8 & 12

10-5 =5

12-8 = 4

 so slope = 4/5

$7 + $0.20p = $5 + $0.30p

Step-by-step explanation:

UPS charges $7 for the first pound and $0.20 for each additional pound.

FedEx charges $5 for the first pound and $0.30 for each additional pound.

Let's take the number of  additional pounds that will make UPS and FedEx cost the same to be p.

$7 + $0.20p = $5 + $0.30p

$7 - $5 = $0.30p - $0.20p

$2 = $0.10p

p = = 20 additional pounds
