Answer: 280 lockers
Step-by-step explanation:
3/5*700= 420 so 420 are being used and 700-420=280 lockers not in use
M = -9 ; solve for m by simplifying both sides of the equation, then isolating the varible

I=PRT/100
1. Make R (rate) subject
R/100= I/PT
2. Substitute and calculate
r/100= i/pt
r/100= 40/400 × 1
(<em>4</em><em>0</em><em> </em><em>i</em><em>s</em><em> </em>from 440-400.<em>T</em><em>h</em><em>e</em><em> </em><em>i</em><em>n</em><em>t</em><em>e</em><em>r</em><em>e</em><em>s</em><em>t</em>)
r/100= 0.1
r/100×100= 0.1×100
r=10% (interest rate per year)
To confirm
I=PRT
I= 400×10/100×1
I= $40 (Interest)
Just take the answer of the subtraction problem and add it to the other number for an answer Example h-7=14 14 + 7=21 h=7
