Question

26. Cheryl paid $35.20 for a strawberry shortcake and 1 doughnut .Ria paid $50.80 for a strawberry shortcake and 10 doughnuts. How much does a strawberry shortcake cost ?​

Answer 1

Answer:

$24.8

Step-by-step explanation:

$let\ strarvberry\ shortcate\ is\ x.$

$doughnuts:y.$

$\left \{ {{x+4y=35.2} \atop {x+10y=5018}} \right.$

$\fbox{ 2 }-0:6y=15:6$

$y=2.6$               $\left\{equation\right\}$

∴$x=35.2-4\times2.6$

$=24.8.$

∴$A\ strawberry\ shortcake\ cost$ $$24.8$

Answer 2

-The correct answer should be 33.47

Basically what I did was subtract the 35.20$ with the 50.80 knowing that the result would give me the prices of 9 doughnuts and I got 15.60 them knowing that that 15.60$ is the price for 9 doughnuts I divided by 9 and I got 1.73$ them I subtract that 1.73$ with 35.20$ that is the price of the strawberry cake and one doughnut and got the final answer would should be 33.47$ if I’m not wrong.

Hope this help you!
