Answer:
Maria bought 8 apples.
Step-by-step explanation:
given:
Apples cost $2 each, while oranges cost $3 each. Maria purchased 10 fruits in total and spent $22.
find:
How many apples did she buy?
solution:
apples (a) + oranges (o) = 10 ------------- eq.1
$2 apple (a) + $3 orange (o) = $22 -------eq.2
first solve orange from eq.1
a = 10 - o
now, substitute orange in eq.2
2(10 - o) + 3 o = $22
simplify:
20 - 2 o + 3 o = 22
o = 2
solve a using o = 2
a = 10 - 2
a = 8
therefore,
Maria bought 8 apples.
