David le Dasha ba ile kwa moletlong wa ditiro tsa mabelo, kwa go nang le ditiro tsa mabelo di le 9. Tiro nngwe le nngwe e lopa dithekete tsa lobelo di le 2 ka $2 thekete nngwe le nngwe. O ka reka le sekgono sa go palama sa $30 se se go nayang ditiro tsa mabelo di le 9. Fa David a reka sekgono sa go palama mme Dasha a reka dithekete, mme ba palama ditiro tsotlhe tsa mabelo di le 9, David o boloka bokae?

An eraser costs $2 and a pencil costs $3. How much do 6 erasers and 8 pencils cost?
Tiro nngwe le nngwe e lopa 2 x $2 = $<<2*2=4>>4.
Ditiro tsotlhe tsa mabelo di le 9 di lopa $4 x 9 = $<<4*9=36>>36.
Ka go tlhapa sekgono sa go palama, David o boloka $36 - $30 = $<<36-30=6>>6.

Six erasers cost $2/eraser x 6 erasers = $<<2*6=12>>12.
Eight pencils cost $3/pencil x 8 pencils = $<<3*8=24>>24.
So, 6 erasers and 8 pencils cost $12 + $24 = $36.
