Answer:

Adam's container

Step-by-step explanation:

Given

Adam

Weight = 3.5\ oz

Amount = \$8.75

Macro

Weight = 3.75\ oz

Amount = \$9.75

Required

Determine the better buy

First, we need to determine the unit cost per oz of each

i.e.

Unit\ Cost = \frac{Amount}{Weight}

For Adam:

Unit\ Cost = \frac{8.75}{3.5}

Unit\ Cost = 2.5

For Marco:

Unit\ Cost = \frac{9.75}{3.75}

Unit\ Cost = 2.6

The better buy of both is the one with the smaller unit cost.

<em>Since 2.5 < 2.6, we can conclude that Adam's container is a better buy</em>

How do you answer a, b and c, answers and also how you worked it out
Kruka [31]

We can either convert to standard form first or convert to a common multiplier, kinda like a common denominator.  The latter makes more sense if they wanted the result in scientific notation, but let's do it that way anyway.

a)

4.5 × 10⁴ + 3.8  × 10³ = 45 × 10³ + 3.8  × 10³ = 48.8× 10³ = 48,800

Answer:  48,800

b)

4.5 × 10⁴ - 3.8  × 10³ = 45 × 10³ - 3.8  × 10³ = 41.2× 10³ = 41,200

Answer:  41,200

c)

7.2 × 10⁻³ + 6.3  × 10⁻² = 7.2 × 10⁻³ + 63  × 10⁻³ = 70.2 × 10⁻³

       = 7.02 × 10⁻² = 0.0702

Answer: 0.0702
