Answer: 28 Brownies and 38 Cookies
Let say the brownies sold for B amount and cookies for C amount. There were 10 more cookies sold than brownies. If brownies sold X piece then, total sales would be:
Sales: (X+10) C + XB
Total sales is $40. Cookies sold for $0.50 each. Brownies sold for $0.75 each. If you insert it all to the first equation, it would become:
$40= (X+10) x $0.50 + $0.75X
$40= $0.50X + $5 + $0.75X
40= 1.25X + 5
1.25X= 35
X= 35 / 1.25= 28
Brownies sold at 28 pieces. Cookies sold at: 26+10= 38 pieces.
Answer:
The first step to solving the equation is:
Hence, 3x + 24 = 42 is the correct option.
Step-by-step explanation:
Given the equation
First of all, we need to apply the distributive law on the left side of the equation to expand the equation.
So the equation would be expaneded using the distributive law on the left side of the equation
∵ a(b+c) = ab + ac
Therefore, the first step to solving the equation is:
Hence, 3x + 24 = 42 is the correct option.
