Question

Ethan is printing some materials for a meeting. If the printing of the first copy costs 1 1/2 dirams and other copies cost 4/5 of a dirham each to print, how much will it cost if he is making 13 copies?

Answer 1

Step-by-step explanation:

Cost of 1 copy - 11/2 diharams

Copy remain to print = 13-1 = 12

Cost for copying rest of the coppies = 4/5 Dirahams

Total Cost for copying = 4/5×12 = 48/5

$\frac{48}{5 } \times \frac{2}{2} = \frac{96}{10} \\ \frac{11}{2} \times \frac{5}{5 } = \frac{55}{10}$

$\frac{96 + 55}{10 } = \frac{151}{10} = 15 \frac{1}{10}$

Answer in decimal 15.1 Dirham
