Answer:
430
Step-by-step explanation:
<u>Given :-</u>
- By selling a watch on 400 and 460’. Loss and profit happened respectively.
- The loss and profit are equal.
And we need to find out the CP .So ,
<u>Let :- </u>
- CP be x
- Profit and Lost be y .
<u>According to the Question :- </u>
460 = x + y <em>( Profit)</em>
400 = x - y <em>( Loss)</em>
<u>Adding both :- </u>
460 + 400 = x + y + x - y
860 = 2x
x = 860/2
x = 430
<u>Hence the Cost price of the watch is 430 .</u>
Answer: I think its $37.84625 according to the working shown :)
Step-by-step explanation:
cost of paper= $5.79, hence 2 is 2 x 5.79= 11.58
pens= $9.25
paperclips= $2.29
calendar= $12.50
Total= 11.58+9.25+2.29+12.50= 35.62
6.25% sales tax on total purchase= 6.25/100 x 35.62= $2.22625
Adding the sales tax: 35.62+2.22625= $37.84625
Answer:
A has 263 calories
B has 257 calories
Step-by-step explanation:
system of equations:
a + 2b = 777
2a + b = 783
I multiplied the first equation by -2 to eliminate the 'a' terms
-2a - 4b = -1554
+ <u> 2a + b = 783</u>
-3b = -771
b = 257
solve for 'a'
a + 2(257) = 777
a + 514 = 777
a = 263
A. 5 invitations
b. 15 invitations
