Amount that Ryan earns if he sells 32 sweaters
= 32 x 34
= $1088
Big difference between the amount on the sweaters and the skirts
= 1088 - 697
= $391
Small difference the amount on one sweater and the skirt
= 34 - 17
= $17
Number of skirts that Ryan sold in May
= 391 ÷ 17
= 23
Number of sweaters that Ryan sold in May
= 32 - 23
= 9
