At Tian Tian Fruits Stall, guavas are sold in packets of 2 and grapefruits are sold in packets of 3. Opal bought 10 guavas and 6 grapefruits. How much did she pay for the guavas and grapefruits altogether?
| Fruits |
Cost |
| One packet of 2 guavas |
$4 |
| One packet of 3 grapefruits |
$5.10 |
Number of packets of guavas
= 10 ÷ 2
= 5
Cost of the guavas
= 5 x 4
= $20
Number of packets of grapefruits
= 6 ÷ 3
= 2
Cost of the grapefruits
= 2 x 5.10
= $10.20
Total cost for the guavas and the grapefruits
= 20 + 10.20
= $30.20
Answer(s): $30.20
