Alex stocks up for winter. He buys 32 cans of vegetables. He pays 80 cent per can for tomatoes and 40 cents per can for corn, fo
lara31 [8.8K]
X = # of cans of tomatoes, y = # of cans of corn

x + y = 32.....y = 32 - x
0.80x + 0.40y = 18

0.80x + 0.40(32 - x) = 18
0.80x + 12.8 - 0.40x = 18
0.80x - 0.40x = 18 - 12.8
0.40x = 5.2
x = 5.2 / 0.40
x = 13 <=== 13 cans of tomatoes were bought

leaving (32 - 13) = 19 cans of corn bought

Emilio's savings account had a balance of $621.96 at the end of July. During August, he made three savings account deposits of $
NARA [144]

Answer:

B. He would still need 51.50

Step-by-step explanation:

First I added up all the deposits Emilio made

so: 621.96+83.11+52.89+307.84=1065.8

then i subtract 129 from the total (1065.8)

which equals 936.8 and I add the 11.5 interest.

which equals 948.3 which is 51.70 less than 1000. Therefore, Emilio still need 51.70 in order to meet his saving accounts goal.
