Seth wants to purchase a new desk. Since he lives near the border of two cities with different sales taxes rates, he decides to compare the total price of the desk from each store.
Store A
Store B
desk price: $289.99
sales tax rate: 7%
desk price: $299.99
sales tax rate: 6.5%
Which statement is true?
OA.
The total cost of the desk including sales tax will be lower at store A by about $9.
OB.
The total cost of the desk including sales tax will be higher at store A by about $9.
OC.
The total cost of the desk including sales tax will be lower at store B by about $12.
OD.
The total cost of the desk including sales tax will be higher at store B by about $12.
O E.
The total cost of the desk including sales tax will be the same for both stores.

The total cost of the desk including sales tax will be lower at store A by about $9.

Step-by-step explanation:

Hi, to answer this question we have to calculate each store price:

Total cost : desk price x(1+ tax rate in decimal form ( divided by 100))

A = 289.99 (1+7/100) = 289.99 ( 1.07) = $310.28

B = 299.99 (1+ 6.5/100) = 299.99 ( 1.065) = $319.48

Since cost B is higher, we have to subtract cost A to cost B to obtain the price difference:

319.48 -310.28 = 9.19 = about $9

So, The total cost of the desk including sales tax will be lower at store A by about $9.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
