Tara's science project was graded based on creativity, accuracy, and effort. If she received a 9.4 for each of the three citeria, what was her total score

Tara's total score = 28.2

Step-by-step explanation:

We are told that her science project was graded based on creativity, accuracy, and effort.

Now, she received a score of 9.4 for each of these criteria.

Thus;

Score for creativity = 9.4

Score for accuracy = 9.4

Score for effort = 9.4

So,

total score = 9.4 + 9.4 + 9.4 = 28.2

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!
