To find the total cost of buying 4 containers of orange juice, we need to substitute x = 4 into the function f(x) = 4.50x - 7.
f(4) = 4.50(4) - 7
= 18 - 7
= $<<18-7=11>>11
Therefore, you would pay $11 to buy 4 containers of orange juice.
To calculate the total cost, we need to use the given function f(x) = 4.50x - 7, where x represents the number of containers of orange juice.
To find out how much you pay to buy 4 containers of orange juice, we substitute x = 4 into the function.
f(4) = 4.50(4) - 7
= 18 - 7
= $11
Therefore, you pay $11 to buy 4 containers of orange juice.
