Nathan bought a pair of boots for $79.95 and 2 shirts for $19.99 each. The sales tax is 7%. How much did Nathan pay for all the items, including tax?

Nathan paid $128.3251 for all the items, including tax.

Step-by-step explanation:

∵ Nathan bought a pair of boots for $79.95

∵ Nathan bought 2 shirts for $19.99 each

→ Find the total price of them

∴ The total price of the items = 79.95 + 2(19.99)

∴ The total price of the items = 79.95 + 39.98

∴ The total price of the items = $119.93

∵ The sales tax is 7%

→ That means we will add 7% of the total price to the total price

∴ Nathan paid = 119.93 + 7%(119.93)

∵ 7% = 7 ÷ 100 = 0.07

∴ Nathan paid = 119.93 + 0.07(119.93)

∴ Nathan paid = 119.93 + 8.3951

∴ Nathan paid = $128.3251

∴ Nathan paid $128.3251 for all the items, including tax.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
