By what percent will the product of two numbers change, if the first number increases by 70%, while the second number decreases

erica [24]

Answer:

The product of two numbers changes by 2% when the first number increases by 70%, while the second number decreases by 40%.

Step-by-step explanation:

Let first number be x and second number be y .

Then product of x and y = xy ......(1)

Given the first number increases by 70%, while the second number decreases by 40% this means,

x is increased by 70% that is

increased value of x = x + 0.7(x) = 1.7 x

Similarly y is decreases by 40% that is

decreased value of y = y - 0.4(y) = 0.6y

New product will be = (increased value of x )( decreased value of y)

= (1.7x)(0.6y)

=1.02xy

Changed Percentage = $\dfrac{\text{new value - original value}}{{\text{original value}}}\times 100$

Substitute the values, we get,

Changed Percentage = $\frac{1.02xy-xy}{xy}\times 100$

Changed Percentage = $\frac{0.02xy}{xy}\times 100$

Changed Percentage = $0.02\times 100$

Changed Percentage = $2\%$

Thus, the product of two numbers changes by 2% when the first number increases by 70%, while the second number decreases by 40%.

You collect a total of $75 in donations from three people. The three donations are in the ratio 4 to 4 to 7. How much is each of

worty [1.4K]

Each smaller donation was for $20 The largest donation was $15 greater than the smaller donation. First, determine the size of each donation. Since they are in a ratio of 4:4:7, it's easiest to add the ratios together (4+4+7) = 15. Then divide the total donation by that sum (75/15) = 5. Finally, multiply 5 by each of the ratios. 5 * 4 = 20, 5 * 4 = 20, and 5 * 7 = 35 So the 2 smaller donations were $20 each, and the largest donation was for $35. The largest donation was $35 - $20 = $15 larger than one of the smaller donations.
