Answer:
Step-by-step explanation:
umm add divide or multiply both numbers
answer
system : 8L+ 4S = 120
L + S = 20
There are 10 small packs and 10 large packs
step by step answer :
to form the two systems, we have to determine the catagories of the 2 equations : one for money and one for the no of packs
after forming the two equations we simply put the numbers in the same order put above on the calculator ( mode 5:1) and the calaculator will answer it in seconds . 10 small packs and 10 large packs.
To check your answer , substitute the letters with their values and if both equations gave you the same value at the end then your answer is correct!
use equation A(t) = a(1+r)^t to solve. you want to find the starting so solve for A
1000 = a(1+.03)^5
1000 = 1.1592740743a
a = $862.61
