Six books at 8 dollars each is equivalent to $48.00
You are only paying 80% of that cost (100%-20%)
Therefore you are multiplying 48 by .8
Your answer should be equal to $38.40
Answer:
3/5
Step-by-step explanation:
the probability of winning + probability of not winning must = 1
these are the only 2 options
2/5 + not winning = 1
subtract 2/5 from each side
not winning = 5/5-2/5
not winning = 3/5
Answer:
profit will be maximized by making 20 doodles and 20 paintings = ($10 x 20) + ($20 x 20) = $600
Step-by-step explanation:
we have to maximize the following equation:
$10P + $20D
where:
P = number of portraits
D = number of doodles
the constraints are:
P + D ≤ 40
P ≤ 30
D ≤ 20
we do not need to use solver or any other type of linear programming tool to solve this, since profit will be maximized by making 20 doodles and 20 paintings = ($10 x 20) + ($20 x 20) = $600
An algebraic phrase or expression is a mixture of integer constants, variables and algebraic operations like addition, subtraction, multiplication, division and exponentiation. In this problem, you need to isolate first what is grouped together or what needs to be done first which in this sentence, "the sum of negative three-eighths and four. By substitution, it would be (-3/8+4). Then you multiply their sum by x so it would result to (-3/8+4)x. After that it is said that you need to minus that to nine times z which is 9z. This will result to an expression like this (-3/8 +4)x-9z. In the simplest term, the answer would be 9/8x-9z.
