At Tian Tian Fruits Stall, grapefruits are sold in packets of 2 and guavas are sold in packets of 3. Fiona bought 18 grapefruits and 6 guavas. How much did she pay for the grapefruits and guavas altogether?
| Fruits |
Cost |
| One packet of 2 grapefruits |
$8 |
| One packet of 3 guavas |
$7.20 |
Number of packets of grapefruits
= 18 ÷ 2
= 9
Cost of the grapefruits
= 9 x 8
= $72
Number of packets of guavas
= 6 ÷ 3
= 2
Cost of the guavas
= 2 x 7.20
= $14.40
Total cost for the grapefruits and the guavas
= 72 + 14.40
= $86.40
Answer(s): $86.40
