Carco uses robots to manufacture cars. the following demands for cars must be met (not necessarily on time, but all demands must be met by end of quarter 4): quarter 1— 600; quarter 2—800; quarter 3—500; quarter 4—400. at the beginning of the quarter, carco has two robots. robots can be purchased at the beginning of each quarter, but a maximum of two per quarter can be purchased. each robot can build as many as 200 cars per quarter. it costs $5,000 to purchase a robot. each quarter, a robot incurs $500 in maintenance costs (even if it is

step-by-step explanation:

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!
