Answer:

Total = \$103.20

Step-by-step explanation:

Given

Amount =\$160

D_1 = 30\% --- first discount

D_2 = 10\% --- second discount

Sales\ Tax = 7.5\%

Required

Determine the amount paid

First, we add the total discount:

D = D_1  + D_2

D = 30\% + 10\%

D = 40\%

If she got a discount of 40%, then she paid 60% (i.e. 100% - 40%)

So:

Amount = 60\% * \$160

Amount = \$96

Calculate the sales tax

Sales\ Tax = 7.5\% * \$96

Sales\ Tax = \$7.2

Total = \$96 + \$7.2

Total = \$103.20

1.  First find the LCD of the two fractions.
They share the denominator 6.
Turn 1/2 into a fraction with a denominator of 6.
2*3=6,  so 1*3=3
3/6
Now add.
Leave denominators alone,  but add numerators.
3+5=8
8/6
Now simplify.
Divide both by 2.
8/2=4
6/2=3
4/3 is your answer or 1 1/3

1 tenth of 70kg is if you help thx
kkurt [141]

it would be 70/100 then it would go down to 7/10 so 1/10 of 70kg would be 7kg because you change 70 you make it a decimal witch is .70 or .7 now make that into a fraction and it would be 70/100 or 7/10 then you take your 7 because its 1/10 of 70. Or you could do it a whole lot easier way and just divide 70 by 10 and get 7. There you have it your answer is 7.

                                        HOPE THIS HELPED!!!

                                                   THANKS!!!
