1. A motorcycle parts store in Quebec has a monthly raffle to boost their sales. Every $100 purchased is worth one ticket. In a certain month,
Gatineau customers have 250 tickets,
Sherbrooke has 170,
Tadoussac has 180,
Rimouski has 160, and
Laval has 190 tickets.
What is the probability that a winner from Laval will win the monthly raffle?
a. 19/100
b. 3/14
c. 1/6
d. 1/5 --- answer
Solution:
step1:
solve for the total number of tickets
Gatineau = 250
Sherbrooke = 170
Tadoussac = 180 Rimouski = 160
Laval = 190
Total tickets
= 250 + 170 + 180 + 160 + 190
= 950 tickets
step2:
solve for Laval winner probability
Laval probability
= 190/950
= 19 x 10 / 19 x 50
= 10/50
= 1/5
2. Maria paid $15.98 for 16 bananas and 8 avocados at Thrifty Foods store. Peter paid $6 for 5 avocados in the same store. How much did Maria pay for bananas and what is the cost of banana per piece?
A. $4.80, $0.3
B. $8.36, $0.5
C. $6.38, $0.4 -- answer
D. $9.38, $0.6
Answer: C
Solution:
Let
a = avocado cost paid by Maria
b = banana cost paid by Maria
step1: equation 1
formulate equation 1
using Maria's purchase
15.98 = a + b
step2:
solve avocado cost using Peter's purchase
Peter paid $6 for 5 avocados
Avocado cost
= $6/5 pieces
= $1.20 per piece
step3:
solve for avocado cost paid by Maria
Maria bought
8 avocados
a = 8 x $1.20/piece
a = $9.60
step4:
substitute the value of a in step3 into
equation 1
15.98 = a + b
15.98 = 9.60 + b
b = 15.98 - 9.60
b = $6.38
step5:
solve for the cost of banana per piece
Maria bought 16 bananas
cost of banana per piece
= $6.38/16
= $0.40 per piece
