Penny has 96 comic books in her collection. Every month, m, she acquires 8 new comics from her monthly subscriptions. The total number of comics in her collection is represented by the expression: 96 + 8m. What is the total number of comic books Penny will have after 10 months?

176

Step-by-step explanation:

96+8(10) can be read as 96 + 8 x 10 multiply 8 and 10 which equals 80 and add it to 96, 96+80=176

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
