Andy o bereka kwa lebenkeleng la didirisiwa tsa tenese kwa lefelong la boikhathollo la tenese. O na le di-racquet di le 12 tse di tlhokang go tlhaelelwa megala. Di le 3 tsa tsone di tshwanetse go tlhaelelwa ka megala ya synthetic gut, di le 5 tsa tsone di tla tlhaelelwa ka megala ya polyester, mme di le 4 tsa tsone di tla tlhaelelwa ka megala ya hybrid (synthetic gut le polyester ka bogare). Go tla tsaya Andy nako e e kana kang go tlhaelela di-racquet tseo tsotlhe fa e le gore o tsaya metsotso e le 15 go tlhaelela ka synthetic gut, metsotso e le 22 go tlhaelela ka polyester, le metsotso e le 18 go tlhaelela ka hybrid?

Greta wanted brownies for her birthday.  She made a batch for herself; one dozen cream cheese swirl brownies.  At her office, they threw her a party and sent her home with 1/2 a dozen brownies.  When she arrived home, her friends were there to throw her a surprise party and had 4 dozen brownies waiting.  During the party, 1 1/2 dozen brownies were eaten.  How many individual brownies did Greta have left over from the entire day?
Andy o tlhaelela di-racquet di le 3 ka synthetic gut, ka jalo go tla mo tsaya ditiro tsa synthetic gut di le 3 * metsotso e le 15 ka tiro ya synthetic gut = <<3*15=45>> metsotso e le 45.
O tlhaelela di-racquet di le 5 ka megala ya polyester, ka jalo go tla mo tsaya ditiro tsa polyester di le 5 * metsotso e le 22 ka tiro ya polyester = <<5*22=110>> metsotso e le 110.
O na le ditiro tsa hybrid di le 4, ka jalo di tla mo tsaya ditiro tsa hybrid di le 4 * metsotso e le 18 ka tiro ya hybrid = <<4*18=72>> metsotso e le 72.
Ka jalo Andy o tshwanetse go fetsa go tlhaelela di-racquet tsotlhe ka metsotso e le 45 + metsotso e le 110 + metsotso e le 72 = <<45+110+72=227>> metsotso e le 227.

Her office sent her home with a 1/2 dozen brownies so she had 12/2 = <<12/2=6>>6 individual brownies
Her friends had 4 dozen brownies and 1 1/2 dozen were eaten so 4-1.5 = <<4-1.5=2.5>>2.5 dozen brownies left
She made 1 dozen brownies and had 2.5 dozen left from the party so 1+2.5 = <<1+2.5=3.5>>3.5 dozen brownies
Every dozen is 12 and she has 3.5 dozen so she has 12*3.5 = <<12*3.5=42>>42 individuals brownies
She has 42 individual brownies plus the 6 individual brownies sent home from work so she has a total of 42+6 = <<42+6=48>>48 individual brownies
