Answer:
B. $19
Step-by-step explanation:
Approximate prices:
1/4 lb ham = 0.25 * $6 = $1.50
1 1/2 lb turkey = 1.5 * $5 = $7.50
1 lb roast beef = $7
3/4 lb bologna = 0.75 * $4 = $3
Add the approximate individual prices:
$1.50 + $7.50 + $7 + $3 = $19
Answer:
Shirt: $45 , Tie: $12
Step-by-step explanation:
Let s be the price of the shirt
Let t be the price of the tie
Given the information from the question,
s + t = 57 - Equation 1
s - t = 33 - Equation 2
We will use substitution method to find the prices.
We will rearranging equation 1.
s = 57 - t
We will substitute s into equation 2.
57 - t - t = 33
57 - 2t = 33
-2t = 33 - 57
-2t = -24
t = -24 / -2
= 12
We now substitute t into Equation 1.
s + 12 = 57
s = 57 - 12
= 45
From here we know, the shirt costs $45 and the tie costs $12
Answer:
48.8???????????????????
Step-by-step explanation:
The amount invested at 4% is $4,200. This problem can be solved by using two linear equation with two different variables which represent the investment's partition and the investment's return. The first equation is x+y=$7,600 and the second equation is 0.04x + 0.05y=$338, then you must substitute the y variable in the second question with the first equation (0.04x + 0.05($7,600-x)=$338). Therefore, you will get a new equation to solve the problem which is 0.04x+380-0.05x=338 resulting x=$4,200.
-28+28=0, and you add 38. 38 degrees.
