Mathematics

lianna [129]2 years ago
4 0

Answer:

Yes, Amanda has enough materials to make the concrete mix.

Step-by-step explanation:

Total units = 1+3+5

                 = 9

9 units = 630kg

1 unit = 630kg ÷ 9

        = 70kg (Less than 80kg of cement, more than enough)

3 units = 3 × 70kg

           = 210kg (Less than 215kg of sand, more than enough sand)

5 units = 5 × 70kg

           = 350kg (Less than 370kg of gravel, more than enough gravel)
