Answer:
Part 1) The price of a USB memory, stick selling at a 21% discount of its market price (m) ------> 0.79m
Part 2) The price or a CD that sells for 21% more than the amount (m) needed to manufacture the CD -----> 1.21m
Part 3) The final value of a painting after its initial value m, increases by 2/5 ----->
Part 4) The total number of markers that Nancy has if she gives away 2/5 of her m markers to Amy ----->
Step-by-step explanation:
Part 1) The price of a USB memory, stick selling at a 21% discount of its market price (m)
we know that
100% is the market price m
100%-21%=79%
79%=79/100=0.79
so
The price of a USB memory with a 21% discount of its market price is equal to multiply m by 0.79
(0.79)*m=0.79m
Part 2) The price or a CD that sells for 21% more than the amount (m) needed to manufacture the CD
we know that
100% is the amount m
100%+21%=121%
121%=121/100=1.21
so
The price or a CD that sells for 21% more than the amount (m) is equal to multiply m by 1.21
(1.21)*(m)=1.21m
Part 3) The final value of a painting after its initial value m, increases by 2/5
we know that
100% is the initial value m
2/5=0.40=40%
100%+40%=140%
140%=140/100=1.4
Convert to fraction
1.4=14/10=7/5
so
The final value is equal to m multiplied by 7/5
Part 4) The total number of markers that Nancy has if she gives away 2/5 of her m markers to Amy
we know that
100% is the number of makers m
2/5=0.40=40%
100%-40%=60%
60%=60/100=0.6
Convert to fraction
0.6=6/10=3/5
The total number of markers that Nancy has is equal to multiply m by 3/5
so
Answer:
Step-by-step explanation:
We can use the following formula to solve this exercise:
In this case "T" is the time in hours it takes to both taps fill the pool working together, "A" is the time in hours for the first tap filling the pool alone an "B" is the time in hours for the second tap filling the pool alone.
We can identify that:
Then, we must subsitute the known values into the formula:
And finally we must solve for "B".
Then we get:
