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? start by substituting the values of 10 pounds of grapes and 0 pounds of strawberries, or (10, 0) into the equation. 2g + 3s = 20 2(□) + 3(□) ?= 20

Explanation:

Step1: Substitute g=10, s=0

$2(10) + 3(0) \stackrel{?}{=} 20$

Step2: Calculate left-hand side

$20 + 0 = 20$

Step3: Compare both sides

$20 = 20$

Answer:

Yes, the point (10, 0) is a solution to the equation, so Rooby would spend exactly 20 dollars.
