If factors are only rounded up, then the estimate is an overestimate. If factors are only rounded down, then the estimate is an underestimate. When some factors are rounded up and some are rounded down, it is harder to tell whether the estimate is an overestimate or an underestimate.
Step-by-step explanation:
Soln
Given
Cp of 1 glass tumbler=80.1000
=Rs 80000
Number of broken glass tumbler=50
Number of remaining glass tumbler=1000-50
=950
Sp of one glass tumbler=96
Sp of 950 glass tumbler=96.950
=91200
Now
Sp > Cp so it is profit
Profit%=sp-cp/cp.100
=91200-80000/80000.100
=11200/80000.100
=14%
Answer:
<h3>C. -51/7=-7.28</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
7x/3+2=-15
7x/3+2-2=-15-2 (First, subtract 2 from both sides.)
-15-2 (Solve.)
-15-2=-17
7x/3=-17
3*7x/3=3(-17) (Next, multiply 3 from both sides.)
3(-17) (Solve.)
3(-17)=-51
7x=-51
7x/7=-51/7 (Then, divide by 7 from both sides.)
-51/7 (Solve.)
-51/7=-7.28
x=-51/7=-7.28
So, the final answer is (C.) x=-51/7=-7.28.
