Mr. Carandang sold a total of 1,790 prints of one of his drawings. Out of all 1,273 unframed prints that he sold, 152 were small

DiKsa [7]

Answer:

Total framed print = 517

Step-by-step explanation:

Framed print:

Small = 23

Medium = 264

Large = 188

Extra large = 42

Total framed print = Small + Medium + Large + extra large

= 23 + 264 + 188 + 42

= 517

Total framed print = 517

Unframed print:

Small = 152

Medium = 544

Large = 496

Extra large = 81

Total unframed print= Small + Medium + Large + extra large

= 152 + 544 + 496 + 81

= 1,273
