Answer:
She added 83 instead of subtracting
Step-by-step explanation:
83 + n = 110
We want to do the opposite to n
We are adding 83 to n. The opposite is subtract 83
83+n-83 = 110-83
n =27
Mia
83 + n = 110
83 + 83 + n = 110 + 83
163+n=193
The cost per foot of redwood and of pine is $3.5 and $1.5 respectively.
<h3>How to solve simultaneous equation?</h3>
let
- cost of redwood = x
- cost of pine = y
50x + 70y = 280
100x + 60y = 440
Multiply (1) by 2
100x + 140y = 560
100x + 60y = 440
subtract to eliminate x
80y = 120
y = 120/80
y = $1.5
substitute y = 1.5 into (1)
50x + 70y = 280
50x + 70(1.5) = 280
50x + 105 = 280
50x = 280 - 105
50x = 175
x = 175 / 50
x = $3.5
