MODELING WITH MATHEMATICS A conservation
photographer wants to print several photographs of
different animals in different sizes. The table shows
the numbers of each photograph size needed. Each
5 x 7 costs $2.25, each 8 x 10 costs $4.50, and each
11 x 14 costs $11.00. Use matrix multiplication to
find the total cost of the photographs for each animal.
5x7. 8x10. 11x14

Elephants 6. 5. 3
Sea lions 10. 4. 1
