Answer: One bag of peaches : $22
Step-by-step explanation:
Hi, to answer this question we have to write an equation for William and Sylvia.
- <em>William: 2 p + 3 a = 17
</em>
- <em>Silvia: 4p + 2 a =22
</em>
Where:
p = price of one bag of peaches
a= price of one bag of apricots
Solving for "a" in William's equation:
2p +3a =17
3a = 17-2p
a = (17-2p)/3
a= 17/3 -2/3 p
Replacing "a" in Silvia's equation
4p + 2 a =22
4p + 2 (17/3 -2/3p) =22
4p +34/3-4/3p =22
4p-4/3p =22-34/3
8/3 p =32/3
p =32/3 ÷8/3
p=4
