Answer:
14, 22
Step-by-step explanation:
x+y = 36
2×x - y = 6
=> x = 36 - y
=> 2×(36 - y) - y = 6
72 - 2y - y = 6
-3y = -66
3y = 66
y = 22
=> x = 36 - 22 = 14
Answer:
Waylon's Purchase will cost $198.05, and section B depends.
Explanation: Section A is 85% of 233 since thats the total, making the answer to section A $198.05. The answer to section B depends because if he wants more school supplies, then yes, he would want to buy more things for better deals. But if he’s on a budget, then he wouldn't want to spend as much money since saving 20% on something over $300 is more than saving 15% on something over $200.
(8.4*10^8) + (4.2*10^7)
= 882,000,000
= 8.82*10^8
