Equation would be y=2x
So how you would use it is let’s say they bought 10
So y=2(10) so 20 dollars for 10 pounds
Equivalent ratios both the numerator and denominator by the same value, e.g.
27/30
18/20
To find the answer you will write and equation in terms of the cost of a bag of chips.
3(cost of milk) + 4 (cost of water) + 8 (cost of bag of chips) = $21.30
3 (2c +1.60) + 4 (2c) + 8 (c) = $21.30 ; Simplify
6c + 4.80 + 8c + 8c = 21.30
22c + 4.80 = 21.30
- 4.80 -4.80
<u>22c </u> = <u>$16.50</u>
22 22
c = 0.75
The chips cost $0.75 each.
The milk costs (2 x $0.75 + $1.60) $3.10 each.
The water costs (2 x $0.75) $1.50 each.
