Rainer bought 1.43 pounds of lunch meat at the store for $10.98. what was the unit rate (price) of the lunch meat?

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
