Answer:

10%

Step-by-step explanation:

let "x" be the percent

then "x" percent of/×/ 15 = 13.50

x%=x/100 :

x/100 × 15 =13.50

x × 15 =13.50×100

x = 1350 ÷ 15

x = 90%

since the pay rate decreased from 15 to 13.50, it means it decreased from 100% to 90%

100% - 90% = 10%

the percent decrease in Martin's pay rate is 10%
