Question

Planks cost $3 each and plywood sheets cost $5 each. Nick purchased 9 planks and 2 sheets of plywood. How much money did Nick spend all together? Explain how you solved the problem.

Answer 1

so if nick purchased 9 planks and they cost 3$ each then you could add 3 nine times or multiply 3x9 which is 27$
now the same with the plywood but i would be 10$ he spent on those
now add 27 to 10 and you get 37$
so he spent 37$ all together

Answer 2

3 x 9
2 x 5
(2x5) + (3x9)
