Rosie measures the height of a candle as it melts. The candle is 22 cm tall when she first lights it, and it melts at a rate of 0.75 cm per hour. Let C represent the height of the candle, and let H represent the number of hours since Rosie lit the candle. Write an equation relating C to H. Group of answer choices

C equals 22 minus 0.75 H

H equals 22 minus 0.75 C

H equals 0.75 minus 22 C

C equals 0.75 minus 22 H

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!
