[Video] Q3: On saturday afternoon, armand sent m text messages each hour for 5 hours, and tyrone sent p text messages each hour for 4 hours. which of the following represents the total number of messages sent by armand and tyrone on saturday afternoon?

Explanation for Question 3 From the Math (No Calc) Section on the Official Sat Practice Test 1

So number three tells us that on a Saturday afternoon, 2 our month sent em text messages each hour for five hours and 3 Tyrone sent P text messages each hour for four hours. 4 We want to figure out the total number of text messages sent by Armand 5 and Tyrone. Right? So we want to see the total number from both of 6 these people. So we should take the total number from Armand and add that 7 to the total number of text messages from Tyrone. 8 So we need to find each person's individual total, 9 and then add those totals together. The reason that we don't want to multiply 10 them is because you can imagine, 11 you can imagine it like Armand and Tyrone have cookies instead of text messages, 12 right? And so if Armand brings five cookies to the party and Tyrone brings 13 10, they would bring five plus 10, 14 15 cookies total. We don't need to multiply them together because there's no kind 15 of exponent exponential relationship between the two. 16 So Armando is sending five or M text messages each hour for five 17 hours. So for five hours he sends em messages each hour. 18 So we multiply those two together and then Tyrone is doing the same thing 19 except for four hours, he's sending P number of text messages. 20 And so when we add those together, we can arrive at the correct answer 21 of C.
