Answer:2
Step-by-step explanation:
Answer:
41.66%
Step-by-step explanation:
Total profit we have to gain =25/100×240 =60
Cost of one item = 240/100 =2.40
Also given that 1/4 of total good are sold with 10% profit which mean profit =
=6.
(Here 1/4 of 100 is 25 and cost per unit is 2.4)
Total money to be recovered from 75(100-25) items =60-6 =54
Let profit percentage to be charged on 54 items be p%.
Original cost =2.4×54 = 129.6
Profit amount =54 =129.6×p/100
p =41.66% =percentage of profit on rest of the goods.
Y = -2(x + 3)^2 - 4
First expand the parentheses:-
y = -2(x + 3)(x + 3) - 4
y = -2 [(x(x + 3) + 3(x + 3)] - 4
y = -2 ( x^2 + 3x + 3x + 9) - 4
y = -2(x^2 + 6x + 9) - 4
Now distribute the -2 over the parentheses:-
y = -2x^2 - 12x - 18 - 4
y = -2x^2 - 12x - 22 Answer
Answer:
18/5 hours or 3 3/5 hours
Step-by-step explanation:
I assume the break is at 7/5 hours.
5 hours - 7/5 hours = 25/5 hours - 7/5 hours = 18/5 hours = 3 3/5 hours
