To find the value of Coach Velez's total bill, first we must figure out how much the total of all of the ice cream sundaes were.
To do this, we must multiply the number of sundaes (8) by the cost of each sundae ($5.35).
8 * 5.35 = $42.80
However, Coach Velez also left a tip of 15%. To find out how much Coach Velez tipped, we have to multiply his regular bill ($42.80) times the amount he is tipping (15% or 0.15)
$42.80 * 0.15 = $6.42
Finally, we just have to add the bill ($42.80) and the tip ($6.42) together to find Coach Velez's total amount.
$42.80 + $6.42 = $49.22
Coach Velez spent $49.22 in all.
Answer:
a) A = kB
b) 20
c) 9
Step-by-step explanation:
A is directly proportional to B when A = 12, B = 3
a) find a formula for A in terms of B
A ∝ B
A = kB
Where k is constant of proportionality
when A = 12, B = 3
12 = 3k
k = 12/3
k = 4
b) find the value of A when B = 5
A = kB
k = 4
A = 4 × 5
A = 20
c) find the value of B when A = 36
k = 4
A = kB
B = A/k
B = 36/4
B = 9
Answer:
P(A) = at most 25 of them like to swim
P(B) = at least 26 of them like to swim
P(A) +P(B) = 100%
=> P(B) = 100-P(A) = 100-38 =62%
=> B is correct
Answer:
y = -4
Step-by-step explanation:
y = -x-3
Let x= 1
y = -(1) -3
y = -1-3
y = -4
Answer:
12
Step-by-step explanation:
-3 * 2 is -6
-6 * -2 is 12
because a negative times a negative is positive
