Option (a) is correct .

Step-by-step explanation:

As given

Enzel goes online to buy a graphing calculator. He finds a site that currently has a promotion of 15% off on all orders over $50.

Enzel decides to buy his graphing calculator, with a price tag of $83, at this site because he knows that he will get the 15% discount when he checks out.

15% is written in the decimal form

= 0.15

Thus

Discount price = 0.15 × Price tag of the graphing calculator.

                        = 0.15 × $83

                        = $ 12.45

Price of the graphing calculator after getting discount = Price tag of the graphing calculator - Discount price .

Put all the value in the above

Price of the graphing calculator after getting discount = $83 - $12.45

                                                                                          = $ 70.55

As given

Enzel pays 4.5% sales tax on the discounted price and pays a shipping fee of $6.35.

4.5% is written in the decimal form

= 0.045

Sales tax price = 0.045 × Price of the graphing calculator after getting discount .

                        = 0.045 × $70.55

                        = $ 3.175 (Approx)

Thus

Total of Enzel’s online purchase = Price of the graphing calculator after getting discount + Sales tax price + Shipping fee .

Put all the values in the above

Total of Enzel’s online purchase = $ 70.55 + $3.175 + $6.35

                                                      = $ 80.07 (Approx)

Therefore the  total of Enzel’s online purchase is $80.07 .

Option (a) is correct .

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
