In order to calculate the total cost of the purchase, we must first assess that there were two items bought, turkey and lamb. Next, we see multiply the cost of the first item by its quantity, so:
cost(T) = 2.15 * 7.89
cost(T) = $16.96
And repeat for the second item:
cost(L) = 1.87 * 7.89
cost (L) = $14.75
Finally, the total cost is the sum of these costs. So
Total = 16.96 + 14.75
Total = $31.71
Answer:
Step-by-step explanation:
$6/(2 DVDs) = $3/DVD, and $8/(4 CDs) = $2/CD
a DVD costs $3
a CD costs $2
Lynn bought 4 DVDs and 2 CDs for 4×$3 + 2×$2 = $16.
Pierre bought d DVDs and c CDs for $20.
d is 0, 2, 4, or 6
c = (20-3d)/2
(d,c) = (0,10), (2,7), (4,4), or (6,1)

Answer:
<h2>0i</h2>
Step-by-step explanation:
The imaginary number has form:
<em>a + bi</em>
<em>a</em><em> - real part</em>
<em>bi</em><em> - imaginary part</em>
<em>i</em><em> - imaginary unit (i = √-1)</em>
We have the number 9.
<em>9</em><em> is a real part</em>
An imaginary part is equal 0.
Therefore the imaginary part of number 9 is 0i.
