Answer:
$57.63
Step-by-step explanation:
For x > 3, the price in dollars Mr. Roshan will pay for x pounds of beef is ...
cost = 4.99×3 +4.49(x -3) = 3(4.99 -4.49) +4.49x
cost = 1.50 +4.49x
Then for x = 12.5 pounds, the cost is ...
cost = 1.50 +4.49×12.5 = 1.50 +56.13
cost = 57.63
Mr. Roshan will pay $57.63 for 12.5 pounds of beef.
answer: 22
15/7.5 = x/11
cross multiply
7.5x = 165
divide by 7.5 on both sides to get the x alone
7.5x/7.5 = 165/7.5
x = 22
the tree is 22 feet
sorry if it’s wrong
X=162, if you multiply 18*9 which is the way to get the answer you get 162
