At School 27, there are a total of 2050 students in the seventh and eighth grade. The eighth grade has 70 more students than the seventh grade. Which system of equations could be used to determine the number of eighth grade students, e, and seventh grade students, s, in the school? Select all that apply. (En la Escuela 27 hay un total de 2050 alumnos de séptimo y octavo grado. El octavo grado tiene 70 estudiantes más que el séptimo grado. ¿Qué sistema de ecuaciones podría usarse para determinar el número de estudiantes de octavo grado, e, y estudiantes de séptimo grado, s, en la escuela? Seleccione todas las que correspondan.)
A. e + s = 2050
s + 70 = e
B. e – s = 2050
s + 70 = e
C. e + s = 2050
e – 70 = s
D. e – s = 2050
s – 70 = e
E. e + s = 2050
s + e = 70

At a grocery store, Ms. Ficke bought 4 pineapples and 2 oranges for a total price of $18. At the same store, Mrs. Doyle bought 5 pineapples and 5 oranges for a total price of $25. Each pineapple was the same price, and each orange was the same price. (En una tienda de abarrotes, la Sra. Ficke compró 4 piñas y 2 naranjas por un precio total de $18. En la misma tienda, la Sra. Doyle compró 5 piñas y 5 naranjas por un precio total de $25. Cada piña tenía el mismo precio y cada naranja tenía el mismo precio.)
Part A
Which system of equations can be used to find p, the cost of each pineapple in dollars, and o, the cost of each orange in dollars? (¿Qué sistema de ecuaciones se puede usar para encontrar p, el costo de cada piña en dólares y o, el costo de cada naranja en dólares?)
Part B
Mrs. Soldo bought 1 pineapple and 3 oranges at the same store. What is the total price, in dollars, of Mrs. Soldo’s purchase? (La Sra. Soldo compró 1 piña y 3 naranjas en la misma tienda. ¿Cuál es el precio total, en dólares, de la compra de la señora Soldo?)
Part A
p = the cost of each pineapple in dollars
o = the cost of each orange in dollars
4p + 2o = 18
5p + 5o = 25
Part B
p = 4
o = 1
1(4) + 3(1) = $7
