Jeanie wrote the expanded form of (0.2) superscript 5 below. 0.2 + 0.2 + 0.2 + 0.2 + 0.2 Which statement is true? Jeanie wrote the expanded form correctly. Jeanie should have used only four factors of 0.2 as the base. Jeanie should have multiplied the base by itself five times. Jeanie should have multiplied 0.2 by 5.

Jeanie should have multiplied the base by itself five times.

Step-by-step explanation:

Given:

(0.2) superscript 5

= 0.2 + 0.2 + 0.2 + 0.2 + 0.2

= 0.2 × 5

= 1

The above solution is wrong

The correct solution is:

(0.2) superscript 5

= 0.2^5

= 0.2 × 0.2 × 0.2 × 0.2 × 0.2

= 0.00032

The true statement is:

Jeanie should have multiplied the base by itself five times.

The base is 0.2 multiplied by itself 5 times

Total number of T-shirts= 200

Cost per T-shirt (without shipping ) = $2.80

Shipping cost per t-shirt ; 5% of a T-shirt = 0.05 *2.80 = $0.14

Total cost of T-shirt (shipping included) = 2.80 +0.14 = $2.94

Markup = 150% of total cost = 1.50 * 2.94 = $4.41

To get the price at which Michelle will sell each T-shirt , add total cost  to the markup; 2.94 +4.41 = 7.35.

Therefore, selling price will be $7.35
