What is the fraction for 6.-40>2

Step 1: Find the total cost of the items costing $48.12,$48.20, and $48.00.

Formula: total cost = price$_1$ + price$_2$ + price$_3$

Substitute: $48.12 + 48.20 + 48.00$

Add the dollars first: $48 + 48 + 48 = 144$

Add the cents: $0.12 + 0.20 + 0.00 = 0.32$

Total cost = $144.32

Total cost: $144.32

Step 2: How much is 8% tax on the total cost.

Formula: tax = $0.08 \times$ total cost

Substitute: $0.08 \times 144.32$

First compute $0.01 \times 144.32 = 1.4432$

Then $8 \times 1.4432 = 11.5456 \approx 11.55$ (rounded to nearest cent)

Total to pay = $144.32 + 11.55 = 155.87$

Tax: $11.55** **Total payment:$155.87

Step 3: Add $146 + 302$ using expanded form (no units specified).

Write in expanded form:
$146 = 100 + 40 + 6$
$302 = 300 + 0 + 2$

Add hundreds: $100 + 300 = 400$
Add tens: $40 + 0 = 40$
Add units: $6 + 2 = 8$

Combine: $400 + 40 + 8 = 448$

Sum: 448
448

Step 4: Simplify $\frac{40}{72}$ to test the statement $k = \frac{40}{72} = \frac{4}{7}$.

Formula: divide numerator and denominator by GCD(40,72) = 8

Substitute: $\frac{40 \div 8}{72 \div 8} = \frac{5}{9}$

Check: $\frac{5}{9} \approx 0.556$, $\frac{4}{7} \approx 0.571$ (not equal)

Statement is false.

\dfrac{5{9}}

Step 5: Cost for 30 min if $40 for 72 min.

Rate per min = $\frac{40}{72} = \frac{5}{9}$ dollars per min

Cost for 30 min: $\frac{5}{9} \times 30 = \frac{150}{9} = 16.\overline{6} \approx 16.67$ dollars

**Cost: 16.67** \16.67
