Question: Latrell wants to buy something that costs $880 before GST. GST is charged at 10%. What is the total cost after GST is added?(1) $960(2) $968(3) $950(4) $965 Solution: Find the total cost by writing and solving an equation:total cost with GST = cost without GST + 10% of cost without GST= 880 +

Question: Factorise out the highest common factor. If the highest common factor is 1, just retype the polynomial.4z² – 10z(1) 2z(2z–5)(2) 2z(2z+5)(3) 2z(2z*5)(4) 2z(2z-3) Solution: REMEMBER : To factorise a polynomial, first find the highest common factor (HCF) of each monomial. Then factor out the highest common factor using the distributive property. First, factorise each

Question: While designing a new dessert menu, the manager of a restaurant offered customers a coupon in exchange for completing a brief survey about their favourite desserts. 10 of the customers accepted the offer.Is this sample of the restaurant’s customers likely to be representative?(1) Yes(2) No Solution: REMEMBER : In a representative sample, the people

How many weeks of school will Suzie have to attend this quarter before she will have taken a total of 6 quizzes?(1) 2 weeks(2) 3 weeks(3) 1 weeks(4) 6 weeks Solution: Write an equation that shows the relationship between the number of weeks Suzie attends school this quarter w

Question: A corporate team-building event costs $3 for every attendee. If there are 5 attendees, how much will the corporate team-building event cost?(1) $12(2) $13(3) $16(4) $15 Solution: Write an equation showing how the cost d depends on the number of attendees. Then solve.d = 3*5d = 15If there are 5 attendees, the corporate team-building

Question: Mia is watching a baseball game. So far, 10 out of 18 batters have gotten a hit. What is the experimental probability that the next batter will get a hit?Simplify your answer and write it as a fraction or whole number.(1) P(hit) = 5/9(2) P(hit) = 5/7(3) P(hit) = 5/1(4) P(hit) = 5/5 Solution:

Question: A 9-pack of hot dogs costs $9.99. What is the unit price?(1) $1.11 per hot dog(2) $1.15 per hot dog(3) $2.11 per hot dog(4) $1.09 per hot dog Solution: REMEMBER : The unit price is the price per item or per unit of measure. Find the unit price. Divide the total cost by the

Question: Solve for h.2h = 18h = ?(1) 8(2) 9(3) 7(4) 4 Solution: REMEMBER : To solve for a variable, use inverse operations to undo the operations in the equation. Be sure to do the same operation to both sides of the equation. 2h = 182h/2 = 18/2 Divide both sides by 2h = 9

Question: Evaluate. 4³ = ?(1) 16(2) 60(3) 64(4) 12 Solution: REMEMBER : An exponent tells you how many times its base is used as a factor.Exponents are used to write repeated multiplication.For example, for a base of 2:2² = 2*2 = 4 2³ = 2*2*2 = 8 The base is 4 and the exponent is
