Plug in x = 7. Then use the order of operations (PEMDAS) to simplify y = 11 - 5*x y = 11 - 5*7 .... x has been replaced with 7 (since x = 7 is given) y = 11 - 35 y = -24
<span>Ok. You would set up the problem like this: 32/x=64/100 and then cross multiply; 3200=64x; divide both sides by 64; x=50. Mary has 50 customers.</span>
