solved by a system of equations in two variables.
$0.05(n) + $0.10(d) = $1.90
n + d = 27
n + d - d =27 - d
n = 27 - d
$0.05(27-d) + $0.10(d) = $1.90
1.35 - 0.05d + 0.10d = $1.90
1.35 +0.05d = $1.90
1.35 - 1.35 +0.05d = $1.90 -1.35
0.05d = 0.55
0.05d/0.05 = 0.55/0.05
d = 11
n = 27 - 11
n = 16
$0.05(16) + $0.10(11) = $1.90
$0.80 + $1.10 = $1.90
$1.90 = $1.90
Answer:
8
Step-by-step explanation:
(dont mind my spelling im bad at that)so seeing that one hot dog is 5 dollors
and two hotdogs would cost 10 dollors and that would leave 20 dollors to spend and seeing that one taco is 2 dollors and 50 cents we need to figure out how many times does 2.50 go into 20 which is 8 so eva can buy 8 tacos along with 2 hot dogs
