Answer:
3 dimes and 10 quarters
Step-by-step explanation:
If you add 7 dimes, then the number of dimes and quarters is the same, and the total increases to $3.50. A dime and a quarter have a value together of $0.35. Since there are equal numbers, the value $3.50 must be made up of some quantity of groups with a value of $0.35. That number of groups must be ...
... $3.50/$0.35 = 10
Thus, there are 10 quarters and 10-7 = 3 dimes.
_____
<em>Using an equation</em>
Let q represent the number of quarters. Then the amount Bess has is ...
... 0.10(q -7) +0.25q = 2.80
... 0.35q - 0.70 = 2.80
... 0.35q = 3.50 . . . . . add 0.70 . . . . . . . this should look familiar
... q = 3.50/0.35 = 10
A. 39.99
b. 39.99 + 0.25(35) = 48.74
c. 39.99 + 0.25(1) = 40.24
First put 54 over X in a fraction. 54/x
<span>Then put 75 over 100. 75/100 </span>
<span>Then you cross multiply. 75(x)= 54(100) </span>
<span>Simplify. 75x = 5400 </span>
<span>Divide. x=72 </span>
<span>Your answer is 72

13+5=18 18-7=11
That’s the answerrrrrrrrrr
Answer:
list B
Step-by-step explanation:
Given that there are two clicks , list A and B.
List A has a click rate of 5% and payment 0.25 dollars
Hence click rate of 1% costs = 0.25/5 = 0.05 dollars
Similarly for list B,
For a click of 10% payment done = 0.35$
Hence for one click payment = 0.35/10 = 0.035
Since both rates have been converted to rate for unit click we can compare both.
List A = 0.05 and List B= 0.035
List A unit click rate > that of list B
Hence list B has the lower cost per click.
