Let S = spoon
Let K = knife
1 knife is thee times the cost of a spoon, so it would be 3S
Now you have 9S + 12K = 82.80
We can replace the K with 3S:
9S +12(3S) = 82.80
Simplify the left side:
9S + 36S = 82.80
Add:
45S = 82.80
Divide both sides by 45"
S = 82.80 / 45
S = 1.84
One spoon cost $1.84
We know one knife cost 3 times as much, so multiply the cost of a spoon by 3:
Knife = 1.84 x 3 = $5.52
Answer:
The cost of 4 medium pizzas:
4 (x - 3)
Step-by-step explanation:
#3
x = the cost of a large pizza
medium pizza costs $3 less than a large pizza. So it's x - 3
If 4 medium pizzas then it will be: 4 (x - 3)
w + 15 since increased by 15 means add on
12y + 11 since product of 12 and y means multiply 12 and y = 12y
one half n - 16 since one half of n and decreased by 1 6 , subtract 16
2b - 6 since Corinne is 6 years younger represented by b - 6
sum of their ages = b + b - 6 = 2b - 6
9h + 40
$ 9 per hour for h hours = 9 × h = 9h plus the $ 40 from carpool
