Pizza is 12. Sandwich is 8. Total for both is 20.

Megan went to the beach 34 times last summer. She went 6 more times in July than she did in June. She went twice as many times i
Irina-Kira [14]
<span>Megan went to beach 34 times last summer.
June =  x
July = 6 * june
August =  2 * june
Thus Let’s find the value of june, which is the value of x as a variable:
Equation:
x + 6x + 2x = 34
Solution:
=> x + 6x + 2x = 34
=> 9x = 34
=> 9x / 9 = 34 / 9
=> x = 3.7778, since this is a decimal, let’s round this off to 3.78
Let’s check our answer
=> 4 + 6(4) + 2(4)
=> 4 + 24 + 8
=> 36 approximately.</span>
