1) Omar sells clothing at a Sunday market. A T-shirt costs \$16 and a pair of shorts costs \$11. He sold 3 T-shirts and 2 pairs of shorts to each of his customers and collected a total \$910 on one Sunday. How many T-shirts did Omar sell?

2) Renjie has three ropes with lengths of 144 cm, 168 cm and 252 cm. He wants to cut the three ropes into shorter pieces of equal length with no remainders.
(a) What is the greatest possible length of each of the shorter pieces?
(b) How many of the shorter pieces of equal length can he get?

\$16X3=\$48 (cost of 3 t-shirts)
\$11X2=\$22 (cost of 2 pair of shorts)
\$48+\$22=\$70 (cost of 3 t-shirts+2 shorts)
\$910/\$70=13 customers
13X3=39 (no. of t-shirts sold in total)

Hope this helped.
