Amount that Oscar earns if he sells 35 jackets
= 35 x 17
= $595
Big difference between the amount on the jackets and the skirts
= 595 - 411
= $184
Small difference the amount on one jacket and the skirt
= 17 - 9
= $8
Number of skirts that Oscar sold in October
= 184 ÷ 8
= 23
Number of jackets that Oscar sold in October
= 35 - 23
= 12
Answer(s): 12
