Need with this question. will give brilliant 1.you want to buy three books that are on sale at 20% off. the original prices of the books are $2.50, $4.95, and $6.00. how much will you save? calculation with distribution (show all steps.) calculation without distribution (show all steps.) 2.you are purchasing four items and want to calculate the tax. the items cost $2.50, $8.75, $3.00, and $10.25. the tax rate is 6%. how much is the tax? calculation with distribution (show all steps.) calculation without distribution (show all steps.)

1. original prices of books: 2.5$, 4.95$, 6$

2.5$:100%=x:20%, This ratio is calculating by multiplying inertal members and that is equal to external members. 100%*x=2.5$*20%, x= 2.5*20/100, x=0.5$ is 20% of 2.5$. So for 1st book you will save 0.5$.

4.95$:100%=x:20%, x=0.99$ is 20% of 4.95$. For 2nd book you will save 0.99$

6$:100%=x:20%, x=1.2$ is 20% of 6$. For 3rd book you will save 1.2$.
All in total you will save 2.69$.

2. Total coast of items: 2.5$+8.75$+3+10.25$=24.5$. The tax rate is 6%.
24.5$:100%=x$:6%, x*100=24.5*6, x=24.5*6/100, x=1.47$
Tax is 1.47$.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
