A photo-mat shop charges

\$ 0.55

for the first photo inside a film, and

40 \%

cents less for each additional photo. How many photos can we develop with

\$ 52.58

Each film costs:

0.55+35 ×(60 \%

0.55 \$

0.33 )=0.55+11.55=12.1\$

per film.

52.58 \$=4 × 12.1 \$+4.18 \$ 4.18 \$-0.55 \$=3.63 \$ 3.63 \$ {/} 0.33 \$=11
