Step-by-step explanation:

A: y = 0.50x + 5

(y= total amount of money)

(+5 = birthday money)

B: (25) = 0.50x+5

   -5                  -5

                20 = 0.50x                gilberto needs to get 40 correct answers

(divided) / 0.50    /0.50

40 = x          

C:

y= 0.50 (12) + 5                gilberto will recieve 11 dollars !

y = 6+ 5

y = 11

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!
