David opened a coffee shop and sold 60 mochas the first day at $2 per cup. he wants to increase the price per cup to increase his revenue. he found out that for every $0.25 increase, x, in the price per cup, the number of cups he sold decreased by 2 per day. how can david find the equation which represents his daily revenue, in dollars, from mocha sales when the price is increased x times?

the correct answer is d

hope this

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!
