Yes it is because if you multiply 3*3=9
then what you do on top you do on the bottom 10*3=30
Answer:
<h2>12.1% profit</h2>
Step-by-step explanation:
Given data
total eraser= 87
cost =$3 each
Total cost of eraser= 87*3= $261
she sold 63 at $3.5
1. sales made for the 63= $220.5
2 sale made for the remaining= 87-63=24
24*3=$72
Total sales made = 220.5+72=$292.5
her profit= sales-cost
profit= 292.5-261=$31.5
therefore the percent profit is
=31.5/261*100
=0.12*100
=12.1%
Answer:
-22
Step-by-step explanation:
Due to order of operations rules, we must perform the subtraction inside parentheses first, getting:
-4 +(3)(-6)
Multiplication comes next:
-4 - 18
and the total value is thus -22.
let x be how much longer she can run the race and still beat her previous time
55(min) + x(min) < 1(hr) + 10(min)
55(min) + x(min) < 60(min) + 10(min)
55 + x < 60 + 10
x < 60 + 10 - 55
x < 15(min)
