Answer:
- pancake: $0.50
- waffle: $1.20
Step-by-step explanation:
You can model the bills using w and p for the price of a waffle and pancake, respectively.
10w + 4p = 14
5w +8p = 10
Subtract half the first equation from the second:
(5w +8p) -(1/2)(10w +4p) = (10) -(1/2)(14)
6p = 3 . . . . . . . simplify
p = 0.50 . . . . . divide by 6
10w + 4(0.50) = 14 . . . . substitute into the first equation
10w = 12 . . . . . . . . . . . . subtract 2
w = 1.20 . . . . . . . . . . . . .divide by 10
A waffle costs $1.20; a pancake costs $0.50.
Seven and seven eighths rounds up to eight. Two and eleven twelfths rounds to three. Estimate equation: 8+3=11. Now you know your answer should be around 11. Then to find your actual answer you have to find the common denominator! If u need anymore help ask me! Hope I helped!
