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)
90% = 90/100 which simplifies to 9/10
