Question

Miranda and Luci went out to dinner. They each ordered the same sandwich and drink, and they left the same amount of tip. However, Miranda got a dessert for $2.95, and Luci did not get a dessert. Miranda tipped 15%, and Luci tipped 20%.

A. - Write an equation that can be used to find the cost of the sandwich and drink.
B. - How much did the sandwich and drink cost?

Answer 1

let the cost of sandwich and drink be X dollar !

so eqn ;

A) 15℅ of X +2.95 = 20 ℅ of X
solving.....

.20x - .15x = 2.95
.05x = 2.95
x = 2.95/.05 = 59 dollars

B) so the cost of both is 59 dollars !!
