Question

if rooby buys 10 pounds of grapes and no strawberries, would she spend exactly 20 dollars? in other words, is the point (10, 0) a solution to the equation? which strategy would you like to use to find if (10, 0) is a solution to this equation? 2g + 3s = 20 plot the point (10, 0) on a coordinate plane. substitute the values 10 and 0 in the equation.

Explanation:

Step1: Substitute $g=10, s=0$

Substitute into $2g + 3s = 20$:
$2(10) + 3(0) = 20 + 0$

Step2: Calculate left-hand side

$2(10) + 3(0) = 20$

Step3: Compare to right-hand side

Left-hand side = 20, Right-hand side = 20

Answer:

Yes, (10, 0) is a solution to the equation $2g + 3s = 20$, so Rooby would spend exactly 20 dollars buying 10 pounds of grapes and no strawberries.
The valid strategy is: Substitute the values 10 and 0 in the equation.
