Please HELP!!! I'll make you Brainliest!!!!Your goal is to save at least $350.00 over the next 7 weeks. How much money must you save each week in the order to meet that goal? Write and solve an inequality. a: 7x ≤ 350; x ≤50b: x ≥ 350; x ≥ 5c: 350x ≥ 7; x ≥ 5d: 7x≥ 350; x ≥ 50Which solution of the equation y= 5x + 3a: (5,28)b: (28, 5)c: (4, 20)d: (3, 19)Suppose tuna is on sale for $0.90 a can, and you have a coupon for $0.40 off your total purchase. Write a function rule for the cost of "n" cans of tuna. a: C(n) = 0.90n - 0.40b: C(n) = 0.40n - 0.90c: C(n) = (0.90+n) - 0.40d: C(n) = (0.40+n) - 0.90

Answer: 1. d. [tex]7x\geq 350; x\geq 50[/tex]2. a. (5, 28)3. a: C(n) = 0.90 n - 0.40Step-by-step explanation:1. Here x represents the saving of one day.Thus, the total saving for 7 day = 7 xAnd, my  goal is to save at least $350.00  ( According to the question)⇒ [tex]7x\geq 350[/tex]⇒  [tex]x\geq 50[/tex] ( by dividing both sides by 7 )Therefore, Option d is correct.2. since, if a point satisfies an equation then we can say that it is the solution of the equation.(5,28) satisfies y= 5x + 3Because at x = 5, 5×5 + 3 = 25 + 3 = 28except this point other points (28, 5), (4, 20) and (3, 19) are not satisfying given equation of line.Therefore, only (5,28) is the solution of line.⇒ Option a is correct.3. Here n represents the number of tunas.And, according to question the cost of one tuna = $0.90⇒ Cost of n tunas = $ 0.90nBut again according to the question,I have a coupon for $0.40 off your total purchase.Thus, $ 0.40 will be less from my total purchasing cost.⇒ The cost of n tunas = $ (0.90 n - 0.4)Option a is correct.
