Harry is organizing a picnic. he can spend at most $24.00 on beverages. iced tea costs $2.00 per gallon and
lemonade costs $2.50 per gallon. if x represents the number of gallons of iced tea and y represents the number of
gallons of lemonade, which inequality shows the number of gallons of each drink that he can buy? identify the
number of gallons of iced tea that harry can buy if he buys 5 gallons of lemonade.
2.5x + 2y s 24; no more than 6 gallons
2x + 2.5 s 24; no more than 6 gallons
2.5x + 2y = 24; no more than 5 gallons
o 2x + 2.5y s 24; no more than 5 gallons

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
