Answer:
x ≥ 15
Step-by-step explanation:
First you need to make an equation for this. If he already has $50 and needs <u>at least</u> 500 and deposits $30 per day we can put the equation as 30x + 50 ≥500. The reason we put a greater than or equal sign (≥) rather than the less than or equal sign (≤) is because Fred needs <u>at least</u> meaning you can have exactly or 500 exactly. To solve this you would have to do inverse operation and subtract 50 on both sides. You should have 30x≥450. Then divide 30 on both sides. Your answer should be x ≥ 15.
The probability would be 6/16 or 37.5% because there are 16 coins in total and 6 of them are worth more than 5 cents. :)
I think the correct answer is the last option. The term to fill in the blank is not one of the choices given. I think the term would be slope. We use slope to determine the actual rate of change over intervals. It is also called the gradient. It shows how the dependent variable changes as the independent variable changes.
Answer:
The correct answer is 60%.
Step-by-step explanation:
We know that the store had a profit of $ 30 for the pair of shoes sold.
Now we must transform that $ 30 into a percentage.
And one of the ways in which we can calculate this percentage is with the following percentage formula:
P is the percentage we want to calculate.
The number B is the profit we have obtained, 30
And number A is the total of the product, 50
Thus:
P= 60 %
Given this information, we can say that the percentage markup is 60%.
