Taylor and her friends are going into a bakery. How much would it cost to buy 5
donuts and 1 cookie if each donut costs $2.00 and each cookie costs $0.75? How
much would it cost to buy 5 donuts and 1 cookies if each donut cost $d and each
cookie cost $c?

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
