Question

The given image shows Shelly’s internet bill. Which of the following operations should she solve first to calculate her bill amount (in $\$$)? Help her find the final bill amount.

• A. $2\times 4,\$75$
• B. $7\times 6,\$50$
• C. $6+2,\$25$

Answer 1

The correct option is B $7\times 6,\$50$

$7\times 6+2\times 4$

In the given expression, according to the PMDAS rule, we first solve the terms with the multiplication operator and then the terms with the addition operator.

When there are two multiplication operations in an expression, we perform the multiplication operations from left to right.

The leftmost multiplication operation in the expression is: $7\times 6$

$7\times 6=42$

The second multiplication operation in the expression is:
$2\times 4=8$

Let’s substitute these values in the given expression and add them.
$7\times 6+2\times 4$

$=42+8=50$

Therefore, Shelly’s internet bill amount is $\$50$.
